Hello,

When running Navigation, my phone reboots frequently (every 30min-1h). One time it just crashed, screen on, in Navigation. I had to remove the battery.

I experience this since I installed Cyanogen 7.1.0, but it was far less often. Now, it's just unusable when driving.

I tried to limit the CPU frequency (underclocking), but it's the same. The phone isn't hot, enough disk space is available.

After reboot, the GPS has a strange behavior. Sometimes it can't enable.... or it make the fix in 5minutes... Is is a clue ?
How can I get a log crash ? Or a kernel trace ?

Thanks !

It depends on how the phone rebooted on what log you can get. If it was a hard reboot (like it was turned off and turned back on), then you can get the log from /proc/last_kmesg, if it was a soft reboot (just went directly to the CM logo) then you can just get a logcat (there are a number of apps to do this).

But I essentially have the same phone as you, and I have never had a problem with it (and I use navigation all the time... one time was on a trip from southern Germany to Copenhagen, Denmark -- that was a long drive). I would highly suggest wiping the /system partition in recovery (found under the Mounts and Storage menu) and reinstalling CM and gapps. This won't cause any data loss.

Did it solve your issue? I have the same problem and this would help me a lot :-)

Has this worked for anyone?

You can try and see if it works very simply. Formatting the /system partition does not cause any data loss. When you are done, reinstall CM and gapps and see if your problem goes away.

I have the same problem. Every day I get a hard reboot, I'm such tired of this.  Would you like to explain which are the step to formatting the /system, please?

I covered that in my first post on this thread (the 2nd post).

I wasn't subscribed to the topic... I'm sorry for my answer delay.

I cleaned datas for Navigation, it was better, but I still encountered some hard reboots as you say (instantaneously stops and restarts).
Then I tried to clean some of my applications (ICS theme, and others unrelated apps) but I got FC of all my remaining applications (I thought I would have better disable the theme before uninstalling it...). By the way, after a reboot the problem was still here.
I tried a restore from a Rom manager backup (I'm used to), but it completely failed. The phone boots, but all my apps are missing.
I need your help. May the backup be broken? I cleaned everything before the restore (except Fat partition). Even the sdext was backed-up...

Any clue would be greatly appreciated !

This is a known problem; certain hardware revisions have overheating issues when the GPS sensor is active for a long time. The only solution for this is a mainboard swap/upgrade

Overheating when using the GPS for a long time is not the issue, at least not on my phone. I see it happening shortly after enabling the GPS. After the reboot GPS works fine and keeps working without problems. Never had this issue in versions prior to 7.2.

[romain145]

I can confirm it's not an overheating issue.
I tried two tests : with and without charging : Same behavior (I thought about voltage stability and/or charging overheating).
Moreover, I never experienced crashes with my older ROM (HTC stock). I do not believe in a hardware issue...

I'll try the latest CM7 "nightly" with a fresh install (not restore from Titanium Backup) to find out if the problem comes from CM7.

[Magpie42]

Had the same problem after downgrading from 7.2 RC2 to RC1 (due to the battery drain issues).
Only thing helped was restoring the RC1 Nandroid.  Since then the problem did not occur anymore,
although I made all the updates (apart from RC2) up to current nightly 2012-06-02.

So perhaps a clean install will fix this.

BTW: I would just go till 2012-05-26, as the latest seems to have a battery problem when using GPS.

I have the same reboot problems on 7.2.0.1 when using navigation, especially when the phone is on battery (ie not plugged) and screen is switched off. The phone will then reboot within a few minutes, in my case. I am using radio 5.11.05.27.

I seem to have solved my problem (although further testing is required).

*** Always make a Nandroid Backup before making any significant changes to your device ***

1. Download Tiamat kernel v.4.1.0 : tiamat-dev (dot) com (slash) bravo (slash)
2. Install from Recovery
3. Reboot
4. Settings - CyanogenMod - Performances - CPU settings - Available governors : SMARTASSV2
5. Download RIL 2.2.1001G : forum (dot) xda-developers (dot) com (slash) showpost (dot) php?p=10382922&postcount=1)
6. Install from Recovery
7. Reboot

Please note that using Tiamat kernel, I'm no longer able to connect to WiFis set to channels 12 and above, so I had to adjust my home wifi accordingly. Apart from that, GPS now seems to work, but I yet have to take my phone on a 1+ hour trip to test it out extensively.

I still have the same reboot problem with cm-7-20120624-NIGHTLY-bravo, and a totally fresh install.

In my opinion it may be linked to the GPS receiver. I also had reboots with others GPS-related applications.

Do you think updating the radio could be a solution? (I have 32.49.00.32U_5.11.05.27).

No, I don't think it's that simple. I tried simply upgrading to the latest radio, and still had the same problem. I downgraded to 7.1 and since then, everything is fine.

I had the same problem. What I did is replacing the gps libraries (gps.bravo.so and gps.goldfish.so) with those of cm 7.1.

Now everything is perfect!

[MrEgg964]

Using the 7.1 libraries as suggested didn't work for me. But using those from ICS did the trick.

I installed this rom : cm-7-20120923-NIGHTLY-bravo.zip
And I'm using these gps libraries : GPSfromICS_signed.zip

I'm using this setup in combination with Fasterfix, and so far so good. I haven't had the opportunity to test it out extensively -- only for a couple of hours -- but I have had no hard reboot this far. The phone would usually reboot after 1 or 2 minutes when on 3G, on battery, screen off. Now it's just fine. Finally
