Can you try with latest upstream git? Some possibly related lockup were
fixed today (see https://bugs.freedesktop.org/show_bug.cgi?id=13326).
Yesterday when I logged in, X got restarted again, I looked in
Xorg.0.log, and dmesg, and there was nothing related to a crash or
restart. The last entries in Xorg.0.log were these:
(II) Configured Mouse: ps2EnableDataReporting: succeeded
(II) intel(0): xf86UnbindGARTMemory: unbind key 0
(II) intel(0): xf86UnbindGARTMemory: unbind key 1
Today's Xorg.0.log doesn't contain the unbind key message:
(II) Configured Mouse: ps2EnableDataReporting: succeeded
An older log (Xorg.20.log) shows:
(II) Configured Mouse: ps2EnableDataReporting: succeeded
(II) intel(0): xf86UnbindGARTMemory: unbind key 5
(II) intel(0): xf86UnbindGARTMemory: unbind key 6
I was not yet able to reproduce the issue today with the debian
package. (I did a dist-upgrade this morning, but nothing xorg related).
I will try the upstream git, but first I need to find a way to tell
wether the bug is still present or not ;)
It happened again, and I got those 2 unbind entries in Xorg.0.log again.
I downloaded latest git, built it and installed it from a text console
(without rebooting). I have run the reg_dumper tool (attached output as
'dump').
After installing the latest git of the intel video driver, I have
restarted X (without rebooting), and I got this in my Xorg.0.log:
(EE) intel(0): underrun on pipe B!
(EE) intel(0): underrun on pipe B!
(EE) intel(0): underrun on pipe B!
...
(II) intel(0): xf86UnbindGARTMemory: unbind key 0
(II) intel(0): xf86UnbindGARTMemory: unbind key 1
I have rebooted, and I didn't get an underrun yet since.
Best regards,
