Since I'm using Ricardos CM9 build I have to use his builds of your kernel. Which were test4 then 7 and now 8.

If you want me to test the versions in between you would've to build them like he does.

Testing this latest kernel v20 over the already impressive kernel V19.4. Currently under ICS latest update 9.2.1.24.

It's noticeable better in responsive and smoothness. No screen tearing under my observation and all apps open and close without issue.

GPS fixed in less than 10sec and games worked great too. I'd test run quadrant score and this is the best score I achieved under 1504Mhz.

Let's hope this is the kernel even ASUS would recommend..

Should your new v20 kernel show its name in the "about" section of tablet settings?

I installed the version for megatron, but it just shows a name similar to the stock kernel.

Also, no undervolting option?

Am I missing something?

Is there a kernel cleaning script available for the TF? I can't imagine all these flashes are great for the device.

With 17c I had some RR's and SoD's, but then I did a cold boot (turn power on with vol_down pressed, then just don't touch anything and wait), reflashed 17c and now it seems to be perfect. Almost no drain with dock, and no RR's or SoD's yet.

I do have a problem with HDMI, no cropped mode possible, even though it's in the menu.

And I can't use OpenVPN. Normaly that worked out of the box (in ARHD).

I'm using ARHD 3.2.2.

Thanks for the hard work!
[Eee Pad Transformer Android Development] guevor:
Thank you so much, really.
[Eee Pad Transformer Android Development] guevor:
I looked at the log and it seems the problem I mentioned earlier. When there are problems communicating with the dock it can not be assured that their status is correct (and not interrupt at the worst time of the suspension) so I added in 19.3 that when this happens, the suspension abort, to avoid greater evils, but unfortunately sometimes the dock is in a state that does not recover (hence left without deep sleep) and added in the 19.4, that in that case, after trying three times, proceed to suspend (but ... can fail).

Anyway, what I will do is check the i2c to see if I can find some way to avoid the problem.
[Eee Pad Transformer Android Development] marcmarshall:
I don't quite understand. Are you saying there is a problem with 20 at this time? Do recommend using 19.4 or an even earlier version until you address the issue?
[Eee Pad Transformer Android Development] guevor:
Well, sorry for my english. What I trying to say is that the problem was always there. Only on 19.3 caused no deep sleep. On 19.4 and 20 is the same, can cause SOD.
[Eee Pad Transformer Android Development] marcmarshall:
I see. So what do you recommend- sleep deprivation or sod? Are the kernels the same otherwise?

Thanks
[Eee Pad Transformer Android Development] guevor:
I recommend V20, it have changes as I indicated on the changelog. Better performance and less ram fragmentation.

The problem of communication should be rare and only on some cases can cause SOD so the probability should be low.

So far, v20 has no RR or SOD. I, however, found that the wifi won't turn off even I set "Keep WiFi on during sleep" to never. It causes battery drain.

v19.4 did not have the problem. Not sure if it is kernel or app related. I have just rebooted the TF and see if it helps.

[Edit 1] After reboot, close the TF on the dock. The wifi stays on even though CPUspy shows 12 min deep sleep. Reboot did not help.

[Edit 2] Reflashed v19.4 did not fix the problem.

[Edit 3] Installed Auto Airplane Mode (from Don) from Google Play. Wifi turns off when the screen is off. Went back to v20.

[Edit 4] Attached a graph to show v20 introduced wifi not turning off issue. Also, how Auto Airplane Mode stops the drain.

Is VPN working with V20?

firstly, I want to that you for the best kernel. Keep up the great work.

I am running Android Revolution HD 3.3.0, with the default kernel VPN connects ok.

When I flash v20, AnyConnect ICS tries to connect but then just returns to the home screen.

Has anyone come across this, I was wondering whether the TUN.KO is the issue for this kernel?

Thanks

Reporting on V20 with Revolver 4 RC3. I had not been able to detect any issues ;)

TF101, B70, Revolver 4 RC3, 216~1200 MHz, default voltages, docked, MiniSD, no SD, no USB

=> No RR, no SOD, no random wake-ups yet, quick WiFi reconnection on wake-up, deep-sleeping, 33 hours up-time and counting...

It seems that some problems are really caused by ROM.

Made a small donation: 5XX17951MG844744B. Cheers.
[Eee Pad Transformer Android Development] guevor:
I have wifi always on (power it off by hand when not needed) so may be a problem undetected. I will look at it.

I do not use VPN, so could someone confirm if it works and in what rom? thanks

Thank you very much.
[Eee Pad Transformer Android Development] gsantovena:
Same problem for me. I'm using megatron, and with version 17c and below AnyConnects works, but with version 20 it doesn' t. AnyConnect just says that some modules can't be loaded and quit. I haven't tried with any 19 version.
[Eee Pad Transformer Android Development] guevor:
A new version for testing.

-I compiled the tun internally (rather than modular) to see if the vpn works.

-Another small change to see if the wifi shuts off automatically when the display was off (if configured for it). It should also improve a little consumption of the battery.

-A fix already used on V18 but removed on V19. I will be putting one by one, to make sure it does not affect stability. (the other changes should not affect stability)

-Load the xpad modules at boot. Make the xbox pad work again.

So I need to prove three things. If it works the vpn, if the wifi is turned off and if stability is maintained, so I can know if was good each of the changes.

Notice that I have not tested this kernel (albeit the changes are well known), because I'm just testing something about stability in long-term and do not want to interrupt.

Thanks

I looked through many of the threads for Bluetooth issues. I'm reporting issues with Bluetooth causing FC on settings. The BT turns on but never lights up blue on the indicator icon, only grey but it does recognize and it does pair with the device. I'm running AOPK B36 and using the 17c kernel. I saw guevor indicated some research into AOPK.

The 17c is phenominally stable so I'm not to worried about it but the my JF3's are worth using.

Now testing 20.1 with Megatron 1.1.4
[Eee Pad Transformer Android Development] guevor:
I found a problem in the compilation options introduced in V20. One of the optimizations was producing at least a bug in iptables and is possible that something else.

I put here a test2 of V20.1, which is identical to the test1 I put before, except that I have removed the optimization.

Please test it with vpn, firewalls, etc...
[Eee Pad Transformer Android Development] guevor:
You mean reconnecting the wifi or 3G?

The V20 have a problem but if the 17 did not work it may be something else.

I do not use VPN so I searched a bit in case there was someone to say something about it and I saw someone say that with the stock kernel, not worked until the last two versions, so there may be some change in the kernel compile options. I revised the source whenever they released a new version, but since I have not used it, I have not looked at his options.

Someone could put the file /proc/config.gz with the latest kernel from asus to check it?

Thanks

It has been reported before, and there must be something wrong with the kernel, but I have nothing to try the hdmi so testing is difficult to me.

When I have more time, it will check if I find the problem, or if anything can be tested about it.

It is probably the optimization problem that I mentioned earlier. If you can test V20.1test2 I posted before, is likely to return to work.

I do not have a wired controller for the Xbox, so I have not tried it. A user tested the changes and said he worked well with Riptide, so I put the changes into the next version.

Memory thrashing in V20.1Test2?

Reporting on V20.1Test2. I experienced slowness as though apps were running out of memory due to thrashing of sort (was viewing a 6.6MB PDF using ezPDF alongside other apps like Tapatalk, GDrive, etc). The other issue was the erratic connectivity of exchange emails (not sure when it started). Attached is a kmsg log - I saw some "Why" and "freezing" messages.

Guevor this is the error for every file that i try to send to other device with bluetooth. TF can receive from other, but can't send because in the other sense can't enstablish connection. Maybe something regarding BT into your Kernel V20 is broken.
[Eee Pad Transformer Android Development] guevor:
I tried the bluetooth with V20.1test2 to transfer a file from my tablet to my HTC Desire (had not used in a very long time) and asked me several steps of approval on both the phone and the tablet. The last step of authorization, when I accepted on the phone, the tablet transfer failed, but trying again worked perfectly. Then I tried the opposite and seamlessly.

I remember having problems in the past, which errors when trying to initiate a transfer, it is possible that some of the authorizations was not well recorded and then everything failed, I have not clear, but in any case the problem might be the rom, because if I could transfer is that the kernel driver works (although do not rule out any problems that might happens after time, like with wifi). In fact if what fails is the sending, but receiving is working, I understand that communication at kernel level is working and the problem should be on the software above it (rom) that not agree to transfer.
