[965gm mesa] XU 13.10 causing frequent laptop (acer 5620) hard lockups.

[Galen Thurber]

since upgrading from LTS to XU 13.04 & then XU 13.10 the acer laptop is experiencing frequent hard lockups.
one source of lockup has been GL screensaver, so I turned it off. Still the lockups happen
Power management for AC is also off.
The laptop does not run too hot, and the lid is up

Is there a daemon that can catch the source of the lockups?

I'm installing gnome system log viewer and are there log search terms to quickly find the trouble?

I've checked the system with chkrootkit but it has a fatal flaw

Checking `aliens'... /bin/egrep: /dev/.bootchart/proc/sysrq-trigger: Input/output error

the same machine does not lock up under Linux Mint 15 MATE. kernel 3.8.0.xx

Memory is tested often. 2GB
Hard disk has no errors and is tested monthly
System has been put through "crashme" and CPU intensive operations in order to raise tempurature, system remains stable.

Most likely times of lockups are:
- system left idle on AC and power manager is set to no suspend & GL screensaver activated (will lockup less often with no screensaver activated)
- view webm or flash videos via browser and have more than ~ 800MB RAM usage
- run glxgears full screen with some RAM usage

resulting hard lockup shows venetian blinds effect on screen.

update:
after several hours of testing glxgears on Linux Mint 15 kernel 3.8.0 the system did not freeze until today,
around 3 min of glxgears usage the system froze extacly like xubuntu.
I will install an older distribution on the test partition to check for stability.
Pity the day I have to only run Vista on this laptop, mercy

[Galen Thurber (godfree2)]

system hangs up under
Puppy Linux 5.6.1 precise (3.2.44)
as well
sigh.

[Galen Thurber (godfree2)]

testing under older kernel
puppy linux racy 5.5
kernel 3.0.66
glxgears
mutiple boots over 3 hours
no freezing
i915 driver active

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

[Galen Thurber (godfree2)]

same freeze under Majaro 32bit XFCE
kernel 3.4.88

[Galen Thurber (godfree2)]

never stated this was a security issue.
Do not change status

[Galen Thurber (godfree2)]

unable to freeze machine under Puppy Precise 5.7.1
kernel 3.2...

seems kernels 3.4 & up are unstable

[Galen Thurber (godfree2)]

I've been retesting the crash under various kernel versions

3.2.0-61 glxgears fatal in under 5 mins
3.2.0-43 glxgear" little longer to fail
3.2.0-24 fails around 21 minutes

puppy racy does not fail
acer racy x org 7.6, mesa 7.10
Linux puppy5620 3.0.66 #1 SMP Wed Feb 27 21:59:56 GMT-8 2013 i686 GNU/Linux

seems like a kernel regression
where should I post these findings?

At this state you know and I know this bug will never fixed or even verified.
There are no number of reports I can make, no amount.
Even apport is buggy.
