Tracking Android build crashing randomly / sgx error

[Thorsten]

Tracking build boots fine despite some minor non working things like bt and setting up email/dropbox/fdroid (no connection despite working wifi possible)

The system crashes randomly after approximatly 10 to 15 minutes sending display to sleep and dropping tons of debug to serial. Log attached.

Also watched this on 12.01-panda-release

Thorsten, do you also see this on our latest landing-panda panda builds?

[Thorsten (kekschen)]

Well latest landing panda (android-build.linaro.org/builds/~linaro-android/landing-panda/) #46 doesn't boot. Despite 4.0.3 binaries it complains about driver unusuable drivers/gpu/pvr/bridged_pvr_bridge.c

SGXInit: Incompatible driver ddk revision (279068)/ device revision (550175)

Board is v A3 es 2.3

We also observed that bug. Used Pandaboard A4 with DVI enabled. Takes somewhere between 5-10 minutes, then it crashes. Doesnt matter if user is inactive, we observed it while playing around with the settings menu, also on the start screen.

On build:
https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc46-tilt-tracking-blob-12.04-release/#build=6

HDMI Display goes dark after around 10 minutes after bootup.
Logs shows error messages related to video driver.
Display remains blank for another 10 minutes and than randomly comes up again.

This is consistently observed.
Logs attached.

This issue is observed for both 4430 and 4460 consistently.

Impact:
Due to this issue unable to use board for more than 10 minutes after bootup. Display goes OFF after around 10 minutes , (serial console is accessible ) - need to reboot now to get display back.

Is this caused by dpms type screen blanking? It might be a workaround to disable screen blanking if so in that rootfs.

This issue is also observed with:
https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc47-tilt-tracking-blob-12.05-release/#build=2

After around 10 minutes of bootup crash is seen and this is consistently observed.

[warmcat (andy-warmcat)]

It might be worth looking into the workaround I suggested a couple of weeks ago, because it probably isn't going to get better on its own.

Abhishek: Do you know what Andy is referring to?

[Alexander Sack (asac)]

abhishek, please update the spreadsheet to refer to bug 920010 assuming its really a dupe. I will mark this as a dupe now!!

[Alexander Sack (asac)]

err ... dupe of older bug 912651
