One possibility is if you've installed the Netflix patch. The patch seems to cause the video camera to FC... Happens on mine. As of yet I don't think there is a fix.
[Acer Iconia A500] Yoda31:
Yes that was it. I removed the file in system/lib and that fixed it. Thank you very much! :D
[Acer Iconia A500] adancau:
Upgraded last night from v1.7 to the latest version. Since then every time I left my tablet on standby for longer periods of time (charging or not) I had it freezing. It wouldn't come out of standby, the screen wouldn't turn on, and the only way to make it work was to force a shutdown by long pressing the power button then turning it back on. Any hints as to what causes it?
[Acer Iconia A500] ribbe82:
I'm still on:

ROM = HV 1.05a

Kernel = 2.2

CPU between 216 - 1200 MHZ on demand

Cleaned cache before flashing kernel

No SOD's

No sudden reboots

Access to market all the time

1200MHZ is smoothh

AD-Hoc WiFi is perfect

So maybe that is the ideal combination for now..

It's really fast, the guy next to me looks at his iPad2 and says: hmm, what you said it costs? :D
[Acer Iconia A500] ahmedfusmani:
Confused

So... I'm running Taboonay 1.1 because a friend could not stop talking about how great it was.. Do I just download and run this kernel as an update through cwm? do I have to completely wipe format etc? I'm running "4.010.38_COM_GEN1" do I need to upgrade/downgrade to "4.010.13" before I do this?

Sorry about the noob question.. hopefully someone will respond. lol..
[Acer Iconia A500] 12013E12T:
I can confirm that.

Back on 2.1 kernal for now since a day or 2 and had no more problems.
[Acer Iconia A500] bvhoesel:
Had some issues with kernel 2.1 (maybe just bad luck). But since several days on 2.3 (and 1.05a). None of those issues so far. Just upgraded kernel and rom. Did not wipe.
[Acer Iconia A500] richardtrip:

how to install

Please, any one can explaine how to install this stuff. I am not expert but I did succeed upgrading the rom to 3.1.

Thanks
[Acer Iconia A500] zoubidou:
very easy.

install and activate root as explained.

install recovery 3.4 as explained

copy the zip file to your external sd card.

2 ways:

1. use a card reader on your pc and copy it to it.

(power down, remove sd card, copy the file to it, reinsert the sd card, power up).

2. navigate to the .zip link with your iconia browser

download the zip

(download a filemanager root explorer or es file manager from the market)

open file manager, go to sd card, download, move or copy the .zip to your external sd card.

external sd card can be found in /mnt/external_sd/

power down

volume- power, until it shows the first lines of cwm (very important)

then install zip from sd card and thats it

reboot

download and install setCPU from market for o/c settings

thats it.
[Acer Iconia A500] samaliset:
Many thanks for your pro;pt answer and I am going to implement right now.

By the way am I going to be able to read and write on an external hard disc. I am asking that because since I did the upgrade and with the NTFS Mounted I can no longer have access to my hard discs.

as i tested the taboonay running on thor's kernel @ 1.4ghz will score minimum 2600 in quandrant, this 1 i get average below 2000, as i notice the result bar, seems like the I/O part & CPU which is the main things to drag the overall mark down, and there is a noticeable increament in 3D part

This kernel helped me see OTA update, stock kernel always says no update.

ROM: stock 4.010.24_com_gen1

Update : 4.010.40

Strange ?
[Acer Iconia A500] sanaell:
and I am gratefull :D

4.010.40 : firmware

2.36.6.4 : kerne

if I update the kernel will I loose some of the firmware updates ? ior not ?
[Acer Iconia A500] xda-dev2k:
I'm glad to confirm this, for the very first time after having updated with every available rom (curiosity kills the cat), this kernel allowed to dounload the 4.010.38 (started from .22). Apart from the versions mismatch, I feel this very very good.

Well done job ;)

Could be off-topic, excuse me just in case...

Remeber to reinstall the default recovery image if you want to succeed in ota update, then you can go back to thor's one once updated...
[Acer Iconia A500] duongla:
I downloaded the update, decrypted it, put into external SD card, flashed back the stock kernel then went to recovery. Updated successfully :)
[Acer Iconia A500] Nequamvita:
updated!

I can also confirm a successful update to 4.010.38!
[Acer Iconia A500] Johnny0906:
Hats off to you guys that made this kernel, the speed is awesome !

Which settings you guys use conservative or interactive? Which one do you think is best? Battery is obviously the issue.

The last time I scored in the 3400-3600 range was overclocked on virtuous picasso based on the leaked 3.1.
[Acer Iconia A500] :
AWESOME!

After Using the various builds on the board, VP 1.08 - VP 1.1, VG 1.08-1.1, etc., I find this kernel to be the fastest and most stable out. I was able to update as well!

Great job Richard! ;)
[Acer Iconia A500] FloatingFatMan:
Wait... So, installing this custom kernel is enabling people to see their FOTA update?

That's kinda freaky! Cool, but freaky! Might give it a go as I'm fed up with waiting. :p
[Acer Iconia A500] cq842000:
This was with virtuous Picasso 3.1 rom and unity v3 kernel. Since the official ota 3.1 my scores all around have taken a dive. I've been benchmarking and overclocking for a very good while now in the laptop and desktop sector, so I know pretty well that synthetic results are synthetic, but they can be a general indicator among similar hardware of a performance issue, bottleneck, defective hardware, bad driver version, etc.

Nice Kernel build. Just installed, and so far its running solid.

After install, did see OTA update. But i cant update OTA always get Red ! lol. But that is not kernel base prob.

75more mv for 40mhz... when the tablet thermal throttles after a couple of min on 1.6....

do you what to commit tablet suicide?
[Acer Iconia A500] agentfazexx:
1.5ghz should be the limit for this tablet. 1.6ghz isn't stable. Really, what's another 100mhz to an already fast ROM?
[Acer Iconia A500] thor2002ro:
1.6 is rock solid on my kernel... but thermal throttle kicks in... and I don't what to mess with it... because it might burn the chip....
[Acer Iconia A500] agentfazexx:
Ever hear of the placebo effect? I bet that's what you're seeing between 1.5ghz and 1.6ghz. ;)
[Acer Iconia A500] thor2002ro:
trust me 100mhz for a arm is a big deal... don't confuse pc_x86 cpu's with arm... "its not the same kind of food...."

I was just saying the temp are high enough and the voltage trade off is too big...

[Acer Iconia A500] goofytim:
What is the best app or widget or status bar icon to show real time CPU usage? I see many out there but don't want to have to try a ton to find a good one. I want to monitor how much CPU is getting used in different apps when its overclocked and I figure someone here knows of a good one. TIA
[Acer Iconia A500] 12013E12T:
SetCPU!

Use the wiget.
[Acer Iconia A500] goofytim:
OK, I'll have to check for that. I have used Set CPU for a while but didn't know there was a widget for it. thx
[Acer Iconia A500] 12013E12T:
Sorry, i have to read more carefully next time,

CPU usage PER app,

That would be watchdog.
[Acer Iconia A500] goofytim:
No problem. I did turn on the SetCPU widget but as you mentioned it was only showing the current usage while sitting on the home screen. I will try watchdog.

One other question I have after installing this custom kernel. A while back I had made some changes to my sysctl.conf to try and improve network performance. Here are the lines I added:

net.core.rmem_default = 256960
net.core.rmem_max= 256960
net.core.wmem_default = 256960
net.core.wmem_max= 256960
net.ipv4.tcp_rmem='4096 87380 256960'
net.ipv4.tcp_wmem='4096 65536 256960'
net.ipv4.tcp_timestamps= 0
net.ipv4.tcp_sack= 1
net.ipv4.tcp_window_scaling= 1
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_intvl = 30
net.ipv4.tcp_keepalive_probes = 5
net.ipv4.tcp_tw_reuse = 1

Do these setting still have any use with this kernel? Meaning are there other optimizations built in already that would make this useless now?
[Acer Iconia A500] Jigga0o7:
Maybe it's just me, but the interactive governor doesn't seem to scale the way it should. Isn't going over the minimum speed for me.
[Acer Iconia A500] btucker2003:
Whats your setcpu settings at? Do you mind sharing? Im only getting quadrant scores of 1500? What gives?
[Acer Iconia A500] sanaell:
so far the ARM CPU inside the table is meant to go up to 2GHz but... the need another cooling system...

it's not overclocking, it's just using the CPU in the range of usage : between 800Mhz and 2Ghz for this one.

but for sure

- battery will drain faster

- need new cooling system to handle the heat

it's hardware problem the speed but hardware about conception of case :D
[Acer Iconia A500] goofytim:
I am running the 2.3 kernel and I have setcpu using a max of 1400MHz. I just ran quadrant and got 2258. I am on stock ROM, 4.010.13.

I have not done anything special with setcpu. I am running interactive and the only profiles i have setup are for low battery, high temp and screen off.
[Acer Iconia A500] btucker2003:
Hmmm... I must be missing something, because Im stretching it more than that on mine now, and Im still only at 1600, I hit 2903 on the Virtuous Xoom Rom a few days ago?
[Acer Iconia A500] Jigga0o7:
Are you on the newest kernel? My experiments have shown that the interactive governor doesnt scale, it just freezes at whatever frequency.
[Acer Iconia A500] btucker2003:
Yep, Im on 2.4...

On the "Main" tab click on the box to the right of the word "Scaling" and youll be presented with about five options. Choose on demand and see how that works. Too bad interactive isnt working properly since it seems to be the best governor for tegra 2.

The latest kernel has my tablet (taboonay rom) stuck at the acer screen (the one from where you boot the tablet to clockwork not the splash screen).

Edit: I have checked MD5 and transfered the file twice once to tablet and once to my USB drive (same results). I also cleared the cache.

EDIT: I can confirm that 2.3 works fine and 2.4 doesn't work on my device.
[Acer Iconia A500] adancau:
Can confirm that interactive governor doesn't work properly (i.e. does not change cpu speed) with 2.4. Had to revert to ondemand.

On the other hand the sleep of death issue seems to have been solved. Thanks.
[Acer Iconia A500] thahandyman:
2.4 is laggy for me compared with 2.3. Tried flashing and wipin a few times.... not sure what changed in this version which may cause lag. Running it with light speed and the 2.3 version was zippy as ****. Anyone else enciunter this and/or have any ideas

[Acer Iconia A500] adancau:
Make sure if you're using SetCPU or another overclocking tool that the governor is NOT set to interactive. Had mine on interactive with 2.4 and it was horrifically slow, then I noticed the CPU was stuck on 200MHz. Changed governor to ondemand and it jumped back to full speed.
[Acer Iconia A500] ribbe82:
No problems here

Yep noticed here also. On demand is my favorite though.

I've tried 1646000, but within 10secs my tab froze, haha! 1200000 is smooth enough for me.
[Acer Iconia A500] monkeychef:
I'm assuming this will work on the Prime Port right? If nobody knows then I can/will test it later.
[Acer Iconia A500] agentfazexx:
+1 there. This has been said over and over.
[Acer Iconia A500] paisanmi:
OMG 1.64GHz :D
[Acer Iconia A500] agentfazexx:
@richardtrip - Can you release more verbose changelogs? Things like "Updated video driver" could be elaborated on more.
[Acer Iconia A500] goofytim:
Not sure I understand this completely. Sure some people may see issues with certain ROMs but I am using interactive on the stock ROM and see no performance issues. I can watch the CPU usage in setcpu and it does not get stuck or show any strange behavior. I ran "benchmarks" using quadrant using both interactive and ondemand and both came in almost exactly the same, less than 5 points difference.

I do see ondemand as potentially using more battery due to the slower recovery from high cpu usage. interactive recovers very quickly, as designed but ondemand will stay at the high cpu state for several more seconds each time. To me this seems like a negative since everyone complains about battery life already.

just my 2 cents!
[Acer Iconia A500] agentfazexx:
What's not to understand? Set it to ondemand and clock speed stays put.
[Acer Iconia A500] goofytim:
what do you mean stays put? it will not stay locked at one speed unless you set the max and min to the same in setcpu. what clock speed are you seeing changing that shouldn't?
[Acer Iconia A500] agentfazexx:
Stays put as in won't drop below the minimum.
[Acer Iconia A500] goofytim:
so are you setting the minimum to something above 216 for normal usage? if so what is the benefit?
[Acer Iconia A500] agentfazexx:
I set min and max all the way to maximum. Battery drain is fine. The point is, set the governor to ondemand, and you won't have the issue. If you don't understand that, I'm not sure how else to explain it.
[Acer Iconia A500] goofytim:
sorry, wasn't trying to be difficult. i just don't set my max and min to the same. i assume the system knows best when to max it out and the rest of the time it is fine to let it rest, save power and lower heat. i get what you are saying. just didn't know people were keeping the cpu maxed all the time. thanks for the explanation.
[Acer Iconia A500] agentfazexx:
I have yet to experience heat or excessive battery drain with maxing out the min/max on this device. My HD2, yes, Acer, no. This thing has a 3500maH battery.
[Acer Iconia A500] goofytim:
ok, that's good to know then. with all the panic i see posted all the time on the forums it just seems like everyone is so concerned about save every ounce of power they can. so keeping the cpu maxed all the time, do you notice things are quicker since you don't have to wait for the cpu to ramp up and down all the time?
[Acer Iconia A500] agentfazexx:
I'd call it smoother, not 'quicker.'
[Acer Iconia A500] monkey10120:
So far 2.4 is running great. No problems yet. Almost no difference compared to 2.3

Also does anyone know why the screen rotation is so slow no matter what your clocked at? I heard that it is the software causing the problem which is making me want to go to the galaxy rom because it is supposed to be "faster".
[Acer Iconia A500] agentfazexx:
As said over and over and over and over....set the SetCPU governor to ondemand.
[Acer Iconia A500] agentfazexx:
@richardtrip-

Here is a suggestion. In the OP, mention that the SetCPU governor must be set to ondemand to fix the lag issues. This issue has been brought up over and over again in your kernel thread, and is taking up space and drawing attention away from legitimate issues.

Hey now this is GOOD NEWS!

Every since I have had this machine I haven't been able to play HD and I mean Hiiiiigh Definition 720 Mp4 files.

What always happens when I played them they fastforwarded by itself but with the MX player you have the option to play via H/S or S/H meaning play with software or playing with hardware software.

So you simple set to (surprisingly H/S) you can now play those HD files that are 720p and also hear the sound and in sync and everything, before I had to use handbrake and wait for 7 hours to decode a movie from 720 HD Mp4 TO 720 HD Mp4 (weird) using xoom setting wit Handbrake.

Now I can watch HD movies on my tab finally without conversion!

Next step MKV files! Can be seen excellent on Mobo player but without sound and with VLplayer you can hear sound and see the image but the video stutters all the time.

Give it up to our developers/modders! That managed to fix one CRUCIAL AND COMMERCIAL function!

Cheers!

[Acer Iconia A500] HIcycles:
Anyone notice a drop in performance after 2.2? I flashed 2.4 the other night, and, while I know benchmarks only tell part of the story, I noticed that, at least with CF-Bench, dropped from 14000 to 13000.

Just curious.

I have also been experiencing the need to delete the dhcp.leases file on an almost daily basis lately to restore wifi. I have forgot my networks, wiped caches, etc. I am running HoneyVillian 1.05a and this seems to have gotten worse with the newer kernels. The fixwifi.apk seems pointless. Any further thoughts?
[Acer Iconia A500] agentfazexx:
Is that ROM any better than Lightspeed?
[Acer Iconia A500] richardtrip:
Maybe you can change the lease time on your router to fix this problem (never had the problem on any of my ap's/routers)

[Acer Iconia A500] formulator_x7:
Just a heads up to those using Taboonay 1.1 with this kernel:

Taboonay has some scripts that will cause issues with governor selection. There are scripts that will try to set the governor to interactive (doesn't exist in this kernel anymore) while awake and conservative while asleep. They also set the CPU frequency to 1GHz when the device wakes up. This results in poor performance when the device wakes up (conservative and 1GHZ on wake) and SetCPU settings being over ridden. I edited both scripts in /system/etc/init.d. Basically I changed occurrences of "interactive" to "ondemand" and the "MAX_CPU_SPEED" variable in the second script to what I like to use in SetCPU (1.4GHz). Much happier now as I don't have to mess with SetCPU every time I wake the device up to get good performance.
[Acer Iconia A500] daveid:
This occurred on several networks, the latest is not mine to tinker with. But at home, this happened and my server is set for 14 day leases, it was happening almost every day. What do you suggest I change it to? Also, why is Acer's fixwifi.apk included in your rom if it doesn't do anything? Or does it need to be manually called upon to work? Is that what the seperate binary is for in the root of flexrom? Also, I have the apk in both flexrom/app and system/app, should I remove one? If so, which?

For what it is worth, it happens when the device is asleep. It just happened again, I disabled wifi, dropped to a term, ran fixwifi, re-enabled wifi, and it worked.

[Acer Iconia A500] formulator_x7:
Sure, assuming you don't want the functionality to switch to conservative when asleep. For me (receive large amounts of push email) this improves battery life as the CPU freq doesn't scale up when I get mail and I'm not using the device.

I installed this kernel on Taboonay 1.1 after reboot I have no internet connection and the wifi settings say error. What did I do wrong and how can I fix it?
[Acer Iconia A500] agentfazexx:
@richardtrip-

SetCPU just randomly set itself to conservative, therefore the clock speed was well below my clock settings. Might want to remove conservative as well.
[Acer Iconia A500] snickle:
I saw you are running the LightSpeed ROM, did you delete the scripts in /etc/init.d? They can interfere with SetCPU.
