app_server crash while changing screen resolutions with intel_extreme

[umccullough]

Another app_server crash into GDB on a different machine.

This machine is a Core 2 Duo with 2gb ram and an Intel G33 chipset.

I was playing a video with VLC and overlay in one workspace, I was compiling in a terminal with a couple others running also in a second workspace, and I had Vision running in a 3rd workspace - and while I was in the workspace with Vision, i opened the screen prefs and increased the resolution to 1600x1200 which caused app_server to immediately crash.

I believe I've seen this happen before when changing screen resolutions on this machine.

The machine had been running continuously and solid for the last couple weeks without issue until I attempted this. See attached screenshots. May be similar or even related to #3282, but I'm not sure.

I will keep this machine in this state in case there is any more info I can obtain and provide.

app_server crash in gdb with backtrace

This looks like a problem with the overlay code. Not sure on which side yet, but I will see if I can reproduce this problem over here; no need to keep the machine running, I think :-)

I seem to have what looks like the same problem running rev 28867 on an Acer Aspire One netbook.

Video hw according to listdev:

device 27ae: Mobile 945GME Express Integrated Graphics Controller

HTH.

Replying to koki:

I seem to have what looks like the same problem running rev 28867 on an Acer Aspire One netbook.

I believe koki mentioned (in IRC) that in his particular case, it's happening consistently on workspace change (similar to #3282) - and he was also playing video - which may be an underlying factor as I experienced crashes either during, or after playing video.

different app_server crash, same G33-based machine

[umccullough]

I added another screenshot from the same G33-based machine with a different app_server crash.

I was trying to stress it a bit, so I was playing a video in VLC (HaikuRocks.mpg) had Vision open, was running dnetc (pegged the CPUs at 100% at idle priority), had a terminal running several "find" commands in a row to keep some scrolling action going, and then started changing workspaces and changing resolutions. I did this for about 5-10 minutes with no chras.

It seemed pretty stable till I let it sit for a coupld mins - and while doing pretty much nothing (no user-actions) it spontaneously crashed.

I moved the cursor around a bit and it then froze.

I encountered a similar crash with the nvidia accelerant shortly after a Tracker crash - see img_1647.jpg in #3289 (​http://dev.haiku-os.org/attachment/ticket/3289/img_1647.jpg)

I am guessing that the first crash shown here (app_server_crash_intel1.jpg) is a duplicate of #3282, but the second crash (app_server_crashintel2.jpg) appears to be a duplicate of #3289 as pointed out by Adek336

[umccullough]

I can't remember seeing any workspace-switching crashes in a while.

Ignore above comment, wrong ticket. I need to retest this more thoroughly again.

Closing - I haven't actually seen this issue in years and it was probably fixed somewhere along the way.
