Anyone else on the Rogers 0.3 kernel having shutdown issues? I seem to be having the issue where it just reboots instead of completely shutting down. Other than that, it seems to be working well.

Keep up the good work Da_G.

Also, this is sort of a silly request, but could you whip up a stock Rogers kernel with the Samsung logo instead of the Rogers animation (like you did in the custom kernels).. I like what you've done in the modified kernels much better.

Thanks!

Shutdown = reboot

I confirm, on Rogers 0.3, shutdown reboots the phone.

Not a big deal as I usually keep my phone on all the time. Actually this is handy! ;-)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
Reboot issue is noted, had it before and it crept back in. Gotta track down the exact cause!

AT&T

Rogers

^ I just built this one 5 minutes ago, don't consider it an official anything, just tooling around. 300MHz on the GPU core with no overvolt, stable for me but others testing have needed a 50mV overvolt to stabilize it. I am trying to find the highest stable levels for day-to-day use right now while comprimising with battery loss.

Will fix the first post links!

@L1near: Yes, actually I was planning to do this :) Going to re-pack the stock kernels with init.d support, adb insecure (for adb root support) and set up to play the stock android bootanimation (which currently is resulting in just the samsung logo as you saw, but should play the standard android bootanimation when the cause for that not working is figured out)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] highlanderx:
WHere can I find the stock voltage table.

DaG. Your latest version works much better. No longer the phone crashes. I had reverted back to stock. I am going to try this one for a few days.

.2 was fastest but BT didn't work correctly. OndemandX resulted in SOD.

.3 simply crashed. Unstable.

Using this one for a while now.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] highlanderx:
Try upping the voltage a bit and see if it helps. If you see skips in quadrant, it certainly diminishes scores.

I am using lagfree in my profile... and it is definitely lag free.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] urkrnboy90:
Well my phone just crashed three times...and for some reason i can't set setcpu to anything below 1.6mhz. I got way better quad scores on bone stock wtf.

And btw, i got quad scores of 2100 running at 1.7 so its not the speed that's the issue.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tejones36:
Has anyone noticed instability during graphics tests? I can't seem to complete a benchmarks on Antutu or Passmark, both crash. (Antutu is fine right up until the knights load). CFbench ran fine, scores of (13704, 4183, 7991) , pretty much a linear rampup which is excellent. As myself and others have noted, Quadrant doesn't work well at all on this phone. Variations of 30 to 50% make meaningful information comparisons impossible. I've had variations from 1600 - 3100 on just the stock kernel.

I'll try some lower frequency runs to see if i can pass the graphics part of the benchmarks, but if that doesn't work - is there s tool to change the gpu OC on the fly? I thought it was bumped up but I need to go check again.

I'll have screenshots posted shortly in the http://xdaforums.com/showthread.php?t=1337529 benchmarking sticky on the general forums.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
Re: the "chop chop knight guys" in antutu, this is the benchmark i'm working on stabilizing for everyone @ 300MHz GPU OC.. it's stable for me now at the current settings but obviously needs a bump here or there for everyone else :)

Currently there is no tool or interface to change GPU frequencies/voltages on the fly, I can look into implementing that for a future version.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] highlanderx:
as long as it is stable.. im up for it....

noticed that lagfree doesn't last through standby!!! jajaja

If i find the right settings for me, could you make me a kernel that is just like that?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
Once I have everything hammered out there will be sysfs tunables allowing you to overclock/undervolt anything you like, via init.d script (and perhaps later a GUI)

The init.d script would be a simple text file with lines like:

echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

echo "ondemand" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor

echo "1782000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

echo "300000" > /sys/devices/video/gpu/gpu0/scaling_max_freq

echo "130000" > /sys/devices/video/gpu/gpu0/scaling_max_voltage

and so on, for everything that is tunable.. then the kernel would come set to all stock values and you adjust as you see fit :) This approach lets everyone tune for what they like rather than me making a bazillion kernels! Also ensures the kernel will always boot up for everyone.

It's in the works.. but it's the weekend now so I'll probably be taking it easy for today, but who knows, drop by IRC and I might be in there posting test kernels per the usual :)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tejones36:
I was sort of hoping you might do something like that - spectacular! I have to admit that I like tinkering/tuning my phone, but at the end of the day it needs to be stable. My preference is definitely to boot stock and then tune personally. If SetCPU or System Tuner Pro can set the speeds at boot, I'd think only one kernel is needed anyway -- I must be missing something here, sorry :). You might consider stock voltages as well since they can be set with either application; except for possibly what you have found to be stable at OC freqs?

Would it be possible to get the same tunables on the graphics side as well? Maybe you just didn't mention it, but I'd like to be able to run completely stock there myself by default as well. Personally I'll sacrifice some FPS for stability - except for a few specific benchmarks the graphics capabilities aren't really being pushed anyway.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
The current apps floating about can adjust CPU Frequency limits and voltage for each frequency, but not any of the other tunables i'll be adding (like GPU freq/volts you mention)

I plan to expose as many of the clocks and voltages as time allows via sysfs interface, and have them all default stock, but there won't be any nice fancy GUI to tune them unless someone makes it :)

Here is the current work in progress, 0.4-pre:

http://www.mediafire.com/?h4kfkl811oh9hcl <--- AT&T

http://www.mediafire.com/?j2nwy8vaspd0a7b <--- Rogers

this is 27MHz -> 1890MHz kernel with 1755/1809 steps added and everything running stock volts except GPU 300mhz 1.25v vs. 266mhz 1.2v. 1809MHz is showing stable.

RAM is a fair bit overclocked here too but running stock voltage!

Reboot on shutdown still occurs 4 out of 5 shutdowns, sleep of death appears to not be occuring in testing (so far)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tejones36:
Hmmm... I've yet to have that happen. I clock back down to stock after benchmarking though. I just tested again with 3/3 success, no reboots on shutdown. .3 kernel, stock (unbloated).
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] phonecurious:

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] L1near:
Well I started to reply and say the Rogers pre 0.4 kernel seemed very stable for me until I put my phone down in the middle of my reply to watch something on TV and it went into a SOD... LOL. Before that it seemed good.

I've been using 0.4-pre for about a day now and my phone has gone into deep freeze several times. I have not adjusted anything. I just use these kernels as is. i think I'm going to have to go back to 0.3. Also, I'm running SkySTOCKeteer.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tejones36:
Running AT&T 0.4-pre, I had the sleep of death once not long after I flashed the phone, but it's been fine ever since. Phone is mostly idle, with most of the time split between deep sleep and 270 Mhz.

AnTuTu is still crashing on the last graphics test. I also noticed I only got about 10 hours of battery life even with 5 hours of deep sleep, so there seems to be either heavier battery drain or possibly I need to clear my battery profile.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] crimpshrine83:
I'm pretty sure we can't...

From what i read, our phone and all the next galaxy variants are using a yamaha sound chip that is arguably inferior to the one in the original galaxy series. The chip is already in use this time around, so unlike the previous so there is nothing to unlock. That's not to say that there isn't some tweaking to the sound chip to be done but I don't think we will see the results seen in the original line. Why Samsung decided to use a different sound chip is anyone's guess. Personally I'm hoping for something like voodoo color to fix the callibration issues that some displays have. Or at least use of the screen tuning application that supercurio has out available from the market. Only time will tell...

May have wrong Kernel and Major Battery Issues

Is this the same Kernel that can be found on addictivetips.com? I used that Kernel and everything works great but my battery dies in about 4 hours after full charge and I am not using phone at all. I am OC at 1.8ghz and its stable. I am in a poor network area but I have the built in battery saver option turned on and have everything turned off after reaching 50% power. Battery feels really warm as well. Any ideas? I would like to use Da G's Kernel and maybe that might fix my issue. I have no apps running or anything else in the background. If I want to switch Kernels, do I have to go back to stock first before doing so?

31 hours wooooow , is it some supercharged battery , r u on 4g or LTE or just in wifi?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tejones36:
I'm using the advanced setting (paid Ultimate version) and did a complete customization, but I think any of the builtins should help.

However, one thing I did note from flashing various ROMs and such - I needed to reset my battery statistics or I experienced the same thing.

1 - Drain the battery almost to empty (10% or so)

2 - Boot into CWM recovery, wipe the battery statistics

3 - Let battery completely drain until *totally* dead

4 - *important* let your phone completely charge to 100%

After that my battery was back to normal, and gained the other ~ 100% (16 hours) with Juice Defender.

Hope this helps.

---------- Post added at 03:59 AM ---------- Previous post was at 03:53 AM ----------

This was mostly wifi, in a non-LTE market, with maybe 4 hours on 4g. 1 hour or so on GPS I think, some benchmarking, etc. Basically normal usage for me on the 2nd day, although I wasn't out of the house much.

If I was going for really high end times, I could have just not have used the phone much during the day and squeezed quite a bit more time out of it. Juice Defender makes a big difference as it manages the data connections, turning them off most of the time when the screen is off/phone idle. I did have the display to fairly dim to help with battery life.

P.S. I'm still having SoD issues with the 0.4-pre kernel. I gave it another go but found it sitting dead later. I did forget to set my minimum clock back to 54 Mhz though - has anyone tried this (or any other workaround) and fixed the issue? 0.3 is completely stable for me (54-1566 Mhz)

This should fix SoD issue and reboot at power off issue, please try 27mhz (270mhz is now default) and see if you still get SoD (you should never at 270)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ma401:
Trying this out (Rogers kernel), I don't appear to get any SoD but I can't get it to stick at 27MHz (using System Tuner) - it keeps jumping back to 270. Am I doing something wrong or is the CPU constantly being used somewhere?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
Certainly is possible something is using the CPU, at on demand i drop to 27mhz and park there quite often. Check Init.d and clear out any CPU scripts, what app are you using to set? I created Init.d script manually here. No problems on sod or power off at 27mhz yet!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bblanski:
Mine is doing the same.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
Sorry, when i asked what app i meant what method are you using to restore CPU frequencies? Init.d or after boot complete (in system tuner options)

Below screenshot set via my own init.d script:
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Charsher47:
Only cpu0 is sticking at 270 for me.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Da_G:
What's system tuner reporting your CPU usage at when one CPU is locked at 270? Note mine is at 3% in the screenshot, which is basically just from drawing the graphs in system tuner. Any higher may cause a core to ramp up.. try uninstalling system tuner and reinstalling! Make sure any /Init.d/ script is wiped in the process, see if that clear a you up.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] zindine:
Stuck at 270Mhz and files with strange permissions

I just flashed 0.4 and I have the same issue with my min CPU speed always revert back to 270.

Reinstalled System Tuner. Not sure how to verify any /Init.d/ script is wiped. Could you give me the full path?

Checked the files in /sys/devices/system/cpu/cpu0/ and in /sys/devices/system/cpu/cpu1/

I executed manually

echo "27000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

echo "27000" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq

But System Tuner would still display 270 upon execution (it's modifying the min_freq automatically)

What else can I try?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Charsher47:
Uninstalled and reinstalled and still the same. The lowest I see it go is 4% but still at 270 MHz. Also, cpu1 gets stuck off sometimes waking up and it won't turn on till I restart. I'm guessing this is like the SOD except only one core since the other is at 270.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] zindine:
I saw that too. System tuner would only report a single CPU. :-(

I'll give that a go today and see how it goes. Thanks!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] tejones36:
.3 worked with system tuner (I have the pro version) or setCPU fine though.

I see the same behavior as some of the above posters. I don't seem to spend nearly as much time in deep sleep than I do @ 270 Mhz, even though my SetCPU profile is set to go down to 27 Mhz. 27 Mhz is also not being hit. This was working fine in .3; most time was in deep sleep (as per my 31.5 hour battery test results ; bottom post.)

So maybe it's working via script, but it was working with the various apps prior to that. Hopefully Da_G will be able to look into it prior to release.

SoD seems to be fixed, although this may just be due to the 270 Mhz minimum.
