[Ubuntu-x-swat] [Bug 932900] Re: Unity freeze, crashes when trying to restart - GPU lockup with IPEHR: 0x7a000002
This reliably happens to me when dragging a firefox window from one monitor to another in 13.04. As above, unity --replace fails and I have to reboot the computer to make it work again. It seems to have started just a week or two ago.

Sorry for the spam, but this just happened again. This time I was dragging a Terminal window around which was running top while the machine was under load (load average between 4 and 5). I didn't cross monitors so that's probably a red herring. Everything froze, but by switching to VT 1 and back (Ctrl-Alt-F1, Ctrl- Alt-F7) I was able to regain control by relaunching unity with LIBGL_ALWAYS_SOFTWARE=1 from that window. I am sure I didn't have this problem just a week or two ago, sorry I can't be more specific other than that I am running 13.04. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/932900 Title: Unity freeze, crashes when trying to restart - GPU lockup with IPEHR: 0x7a02 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/932900/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

This happens for me with several applications, e.g. glxgears, cheese, flash 11.2 r202 in firefox (but not in google-chrome with pepper flash) on 13.04.

I do not know if it will help either, but replacing sna with uxa in /etc/X11/xorg.conf ( or creating a new file with these contents: Section Device Identifier intel Driver intel Option AccelMethod uxa EndSection ) will at least make gnome-shell / unity / ... run. The problem: graphics problems (transparency, smoothing, performance, ...). My graphics card is defined as Mobile Intel® 4 Series Express Chipset Family in Windows, as Mobile Intel® GM45 Express Chipset x86/MMX/SSE2 in the Settings and yells about i915 hangs in dmesg on boot-time when running with SNA. I would like if there will be a fix for that without changing the AccelMethod option. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/932900 Title: Unity freeze, crashes when trying to restart - GPU lockup with IPEHR: 0x7a02 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/932900/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I don't know if that will help, but I have the same intel_do_flush_locked io error sometimes. I create a java program under eclipse using lwjgl (OpenGL version: 2.1 Mesa 8.0.4). And I would greatly appreciate any work around the problem for sure!

In checking Ursula's i915_error_state, she doesn't have IPEHR: 0x7a02 so we're treating it as a different bug for now. Giovanni, I've put mesa 8.0.3 into precise-proposed. I would suggest your next step (if you're still reproducing this bug) is to update your mesa to t he one in proposed and see if that resolves the lockup issue. ** Summary changed: - Unity freeze, crashes when trying to restart - intel_do_flush_locked failed: Input/output error + Unity freeze, crashes when trying to restart - GPU lockup with IPEHR: 0x7a02 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/932900 Title: Unity freeze, crashes when trying to restart - GPU lockup with IPEHR: 0x7a02 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/932900/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
