Bug 20994

I'm not supporting NetBSD. Assign back to me if you reproduce this on Linux.

Hello:

linux-2.6.29.1 with intel driver 2.7rc2 as of commit: 10b5014c42dc055d9559ee112cc7a017e887d813 Not using KMS

Xorg from Debian experimental and the rest from Debian sid. This is xserver 1.5.99.902-1 with libdrm and libdrm-intel 2.4.5 and mesa 7.4. I have EXA acceleration with DRI disabled, Xorg log attached.

I'm having a very similar backtrace:

This happens to me when I play a video using codeine (xine backend) for the second time. I had similar crashes with 2.6.1 intel driver thus I moved to a more recent version, but still the same problem.

Mind that I use vga=0x318 as boot parameter and hence vesa console. Feel free to request any information.

Xorg log

Sorry, I forgot hardware:
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 03)

Toshiba laptop intel core 2 duo.

The "OS" for this bug got changed from NetBSD to OpenBSD, but the new followup report is for "Linux". Since it is now Linux, I now re-add Gordon to the Cc.

I'm not sure if you two are with the same bug. Jeremy, can you reproduce steadily with playing video?

I can't reproduce by playing video. I am not sure how to reproduce it. It has happened maybe 15 times over past two weeks. Just happened again this morning. Back trace of today's Xorg core dump looks the same. I have tried xf86-video-intel-2.6.99.902 and now xf86-video-intel-2.6.99.903 but they don't even detect a screen so X.org fails. At least 2.6.3 partially works. Since my backtrace shows libdrm, I am now trying with libdrm 2.4.7 and see if that helps.

Should I open a new ticket to track down why xf86-video-intel-2.6.99.903  doesn't work (no screens found)?

I am running xorg server 1.4.2 -- I am guessing that doesn't matter since xf86-video-intel configure, build and run didn't complain about old Xorg.

yes, please. You could refer to http://intellinuxgraphics.org/how_to_report_bug.html.

Adjusting severity: crashes & hangs should be marked critical.

    Hold reference to video binding table until all rects are painted.

but it's not the reporter's bug at all.

It is unhelpful to keep these bugs open on known buggy versions of the drivers simply because the infrastructure to test fixes is lacking. Hopefully the situation will improve in the near future and we will be able to start work again on an updated userspace.
