reviewing people last.kmsg files zram was causing memory corruption which was then causing phone freezes / shutdowns, UV could be causing freezes but zram has been identified as an issue hence was removed from the release kernel. :(

if you do have any freezes / crashes post your last.kmsg file and we should be able to see if its due to mem corruption i.e. zram :)
[HTC Sensation] Jose2k:
Check the OP,there is a First Time / Reset kernels, it should solve your status 7 issue .
[HTC Sensation] ifti_a:
hi

do i post it after a reboot or in recovery ?

also could you post the commands for it in recovery if you dont mind please!

i have adb installed

thanks in advance
[HTC Sensation] PaulGiz:
If you pull your battery, last.kmsg is lost so... Try to reboot phone by pressing volume up, volume down and power simultaneously. It often gets you back up and running.

The last.ksmg file will be in the /proc folder. You can pull via ADB or just copy it with ES file explorer. Remember to stuff it (.zip .rar) or you won't be able to upload it to the site as it's too big for a .txt file on XDA forum.

If you reboot it again it will go back up. Sensation has a flaw in reading battery stats

ive gone through this a couple of times, im quite new to kmsg files but i cant really see any crashes, the restart looked like it was asked for by button press.

although your log is littered with:

PM: Device alarm failed to suspend: error -16

not sure what that means. need faux or kohr-ah to help.. :(
[HTC Sensation] jomblass:
Ah ok... So that means 2.5r is the improved version of beta6... Now i get it...

These random freezes that i read, are they using the 2.5r?...

I'm using the xda app so i'm not able to see their sig... I just wanted to be sure that the jump from beta6 to 2.5r is a good choice..no problem in beta6 so far aside from camera hang up with power off.... So anyone please enlighten me. Thank you...
[HTC Sensation] Kohr-Ah:
2.5r is very very stable. Just don't undervolt if you do. That seems to be the cause if most problems

Sent from my HTC Sensation in UR-Quan subspace.
[HTC Sensation] Hawke84:
random freezes were traced back to being zram causing memory corruption, 0.25r has zram disabled so u shouldnt have any of the ramdom freezes, if you do please report!

---------- Post added at 02:25 PM ---------- Previous post was at 02:23 PM ----------

i disagree, ive not seen any proof of UV being the root cause of issues,

im still learning so correct me if im wrong..

im on -50mv and all is happy
[HTC Sensation] Mathias1:
I've been running 2.5r for a couple of days now and no freezing or shutdowns yet! =)
[HTC Sensation] frans-jan:
I already asked , but got no reply.:( so I try it one more time

I use the app . ledmeknow. It flashes the button led,when I have a missed call, which I find very useful.

however with the latest faux kernel this doesn't work anymore. prob because of the dynamic button light.

Is there a way to disable this dynamic button light, so I can use the final release, cause at the moment I'm using the beta 6. (which by the way works OK for me) but i like to use the latest final.

I undervolt myself but I see a common response of not undervolting for those with issues and they said the problem has hence stopped.

[HTC Sensation] silverdart:
How about this!

Every program is going to put a drain on voltage. For instance, if ZRAM is looking for a certain amount of voltage and it is not there then it is going to crash. I hope no one thinks that you can just undervolt and there will be no consequences. I tried -75000 undervolt and it sent my phone into bootloops. You are not going to get proof that undervolting has caused a crash in a message but it is going to cause other programs to crash and thus you will get your message. If I am wrong please some electrician correct me.
[HTC Sensation] Hawke84:
ah ok so zram may be ok if you dont UV, there is hope :D
[HTC Sensation] Jrbourque:
When I flashed 2.5r and went into oc app built into 4.1.7 I had to change to intellidemand for awake should I have changed the sleep to intellidemand too or keep it whatevr it was at ?
[HTC Sensation] TheUntouchable:
Are talking about deamon controller? You have to push the bypass button too :)
[HTC Sensation] Jrbourque:
Ahh ....thank you very much
[HTC Sensation] Hawke84:
so was uv the cause of the zram memory corruption we were seeing in the kmsg's?
[HTC Sensation] PaulGiz:
Yes, it MAY be okay. It is probably phone dependant. I got freezes and one hard crash on b7 with no UV. Other people had no problems at all.

Best course of action would be to try it out. If you're lucky, you can have the best of everything. If not, released version is nice. You only take a performance hit when a lot of stuff is running.

P.
[HTC Sensation] ifti_a:
well I'm using b7 with no UV.

I was using 2.5r final with UV which was fine also

before final I had b7 with UV and it was giving me probs

b7 no UV is fine so far I'm waiting for a crash but its not happening lol
[HTC Sensation] silverdart:
Food for thought!

I'm thinking that it might not be phone dependent but the other programs that we install. All of us have different programs and some programs may be pulling more voltage than others. If you look at some of the photos that people have posted you can see that while the phone is asleep there is a large drain going on. Maybe the combination of these draining programs along with ZRAM and/or undervolting are causing the problems. Maybe we shoUld think about OVERVOLTING to compensate for an abundance of draining programs that we install. HAS ANYONE DONE THAT?
[HTC Sensation] ifti_a:
no don't think anyone has

maybe you could try it, lets us know what happens ?

just keep the ice nearby.....
[HTC Sensation] Hawke84:
That's interesting thinking. I'm not a fan of overvolting, don't want to risk frying the chip..
[HTC Sensation] Catnap:
Overvolting won't do anything - if your CPU cannot handle stock frequencies at the manufacturer's default voltages then it is faulty and should be returned for service. It's not the applications that you're running causing different power drains etc.

For example- using the camera/camcorder is very battery-intensive. Games too. Do these two usage scenarios cause the system to crash when undervolting? No? Then background apps which run while the screen is off definitely will not either.
[HTC Sensation] McLongDong:
I gave a huge compliment to beta7 kernel but it keeps crashing. Now back to the ultimate version and so far it has been no problems. 100% battery still with 5 hours of very minimum usage. No lag either :D
[HTC Sensation] silverdart:
GOOD LUCK!

There you go! "If your CPU cannot handle stock frequencies at the manufacturer's default voltages then it is faulty and should be returned for service." Don't blame it on ZRAM!
[HTC Sensation] Catnap:
Unless there is a problem with ZRam in general :-P

In which case, all bets are off. This is most likely why Faux removed it from 2.5r; he's not sure about it after seeing memory corruption in kernel logs.
[HTC Sensation] silverdart:
Oh Well!

We know that FAUX123 removed it at the reporting of some users. Other users that do not undervolt are reporting different, myself being one of them. So the only questions left are the reasons why and since all my thinking has been disputed and nullified I think I'll just enjoy my ZRAM since I am one of those "lucky ones."
[HTC Sensation] Catnap:
For what it's worth, I've been using 2.5r for 3 days and now it's settled and the battery is calibrated, it's great. I'm on holiday so the camera and camcorder are in constant use all day as well as Maps and background sync and I can still use it a lot and get back to the hotel with 30%+ remaining.

No crashes, reboots or black screens- and I was getting a lot of those when using the camera with various Bricked versions.
[HTC Sensation] Catnap:
Yep, pretty much :-)

I'm sure he'll find a fix for those outlying cases at some point. After all, he understands this a lot better than 95% of us.

Hello guys... Thanks for the quick reply... I think i'm gonna give 2.5r a try...

Before that..i can see that there are 3 versions of this 2.5r... Standard, extreme and ultimate...

Now which of these 3 are you guys using with the most stable and most battery efficient version...

I might also try UV.. i downloaded a zip file from ziphmonger that is flashable... The -50mv version...are you guys familiar with this?.. are these zip files working... Thanks again in advance...

I still haven't figured out why the UV script of zimphishmonger doesn't work for me. The permission is wrong, and even after I fix the permission, it still doesn't work...

Flash a stock rom, then flash the kernel. The scripts should work after that with correct permissions.

[HTC Sensation] scm_crash:
So here's something weird. Lately my phone was discharging REALLY fast. I looked at the processor usage and it was pegged at 1.5GHz at all times no matter what governor I used... The phone was REALLY hot. This was with bricked 1.4r which I've been using for a few weeks with no problem. (I refuse to upgrade when the phone is working perfectly.)

I wiped and started from scratch... Same thing. I don't know what the deal is.

So I decided to ditch bricked 1.4r for the latest stable Faux Kernel. Downloaded it today, installed it, and it's a beaut. However, it doesn't seem that CPU1 is going offline in FauxClock. But I believe that's FauxClock that's keeping it awake.

Anyway, so far so good. Glad to be back. I know that Faux and Show-p have their differences, but it would be awesome if they worked together... (But I'm not trying to start anything. I just heard there was bad blood or something. Maybe I'm wrong?)

Anyway, I'm on IntelliDemand @ 1.18 GHz with no issues so far. Good work. :)
[HTC Sensation] McLongDong:
Where's the post to get the flashable file? What does UV do to help your phone?

Thanks for the reply guys...

Another question.. how do i know if zimpishmonger's flashable UV script is working?... When i flashed it, i system mount first and there was no error...does that mean it's working?...

if you check your VDD table before and after flashing, thats how i did it. im at work at the moment and cant use my phone and cant remember off the top of my head where the VDD table is. if you basically open that and compre it to the stock VDD table (hopefully find that somewhere in this thread) then you'll know :)

[HTC Sensation] PaulGiz:
I so want FauxClock to work, but every time I install it, every version, I'm suspicious. Either the kernel isn't reporting in a way FauxClock can read properly, or it is interfering with kernel operation.

I don't play games, so I don't need to control GPU. I can't undervolt anymore so I don't need UV control. I don't use profiles anymore because "intellidemand" governor takes care of all that, so in the end I prefer to lighten my phone and just set min/max clock and let it go.

OC Daemon with bypass is more than enough, that's what I use. I've considered setting min/max clock right in code to eliminate even that.

Lighter is better. Less is more.
