Thank you Faux!

So I guess the default table is this:



I was at 864mhz/-75mV on latest ARHD 3.6.13, until I decided to raise clock to 1.02ghz and had a couple of reboots during high cpu usage.

Probably the -75mV undervolt was way too low for 1ghz, when I upvolted to -50mV I got no issues.

Anyway I just wanna double-check my default voltages are the same with your kernel stock ones so I could correctly undervolt :)

I have been experiencing a couple of reboots lately, at first I thought it was the uc/uv combination but I just got one with 1.18GHz/-25mV. It seemed to be a "hot" reboot since the screen went right to the white bootscreen and both system tuner and on settings menu gave me an uptime of 35 hours!

(the only way to understand that I had a reboot was missing recent apps when I long-pressed home button and a widget missing from widgetlockscreen -it ends up missing every time after a random reboot)

It happened around the same time Juicedefender was about to enable flight mode for it's night schedule so I thought that JD had something to do with it. Unfortunately I couldn't find the last_kmsg.

I then tried to disable JD and the moment I enabled it back I got another reboot, this time screen blacked out before booting. I was able to pull the last_kmsg this time.

Please bare in mind that yesterday I spent around 6 hours of testing A LOT of apps (~200), also uninstalling most of them, stressing the CPU a lot, so I'm beginning to think that either JD, or another app is causing this.

Any ideas what could be the problem? My config is in my sig :)

Thanks in advance :)

You have a memory leak...

[159331.563659] mpdecision: page allocation failure. order:4, mode:0x44d0

at some point, you ran out of memory so mpdecision couldn't allocate memory for a while. I was surprised how long after the first warning before your phone reset / rebooted...

Thanks for the swift response! Any way to troubleshoot what's causing this?

Could reflashing rom or wiping cache/fix permissions help?

Edit: coincidentally (or not), these issues started around the same time I started using system tuner... uninstalled, back to FauxClock and monitoring. If reboots still happen I'm down to reflashing the rom.

This may have been answered before, but;
On ARHD4, there was a bug that caused the phone to freeze when you had the camera-app open and the screen-timeout locked the screen.

Has this been fixed?

This has not been fixed. So close camera before screen off. I will look at it for the next version.

You could also use an app called appautosettings which lets you (among other things) select to have screen timeout disabled for any app you want!

Keepscreen does the same thing and possibly is a lot lighter as an app, although keepscreen disabled my autobrightness and only gave an option to set brightness at maximum or minimum :/

BTW, after I got rid of system tuner, no more restarts or reboots even when running @864mhz with -75mV. Fingers crossed!
