Bug#693083: System freezes with graphics going down [black screen].
Package: linux kernel
Version: 3.2.0-4-686-pae
Whole system freezes with no apparent reason and the screen "looses input signal" [from the system, just like in the ACPI energy saving mode]. There is no particular time for this to happen and it's unpredictable. It *usually* happens when I play some video streams on other workspace [in XFCE4] while writing some text on the first workspace [in some text windows - IM/web browser, etc], or just when I switch workspaces with mouse going above the left/right edges of the screen [XFCE's workspace auto-switch].
Everything worked fine with previous kernel version, graphic drivers
were not changed, no XFCE4 updates. It all started after I received kernel update [from 3.2.0-3-686-pae to 3.2.0-4-686-pae]. Unfortunately, I don't have an old kernel in place anymore.
I use standard [dpkg -l | grep intel]:
xserver-xorg-video-intel 2:2.19.0-6 driver and
libdrm-intel1:i386 2.4.33-3
The card is [lspci -v | grep VGA]:
00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated
Graphics Controller (rev 02) (prog-if 00 [VGA controller])
Debian GNU/Linux Testing [Wheezy], kernel 3.2.0-4-686-pae [installed from the kernel metapackage].
This bug is critical to me [a deal-breaker]. When it happens I can't do anything and it doesn't leave any trace in logs. I am unable to reproduce it.
EDIT: It actually hung up on me while I was writing this very bug report. Same thing, different kernel version this time: 3.2.0-4-486.
