Bug#382120: xserver-xorg-video-i810 (experimental) leaves video in bad state

["H. S. Teoh" <hsteoh@quickfur.ath.cx>]

Package: xserver-xorg-video-i810
Version: 2:1.6.1-2
Severity: normal
Tags: experimental

Hi,

Just thought I should let the X team know, that although the i810 driver
in experimental fixes the ValidatePci() bug (see #345914, etc.), now it
has problems terminating (e.g., logout, or ctrl-alt-Backspace).
Sometimes it leaves the virtual terminal in a bad state, so that it
cannot be restarted: subsequent attempts to start the X server gives:

	(WW) xf86OpenConsole: setpgid failed: Operation not permitted
	(WW) xf86OpenConsole: setsid failed: Operation not permitted

Other times, it leaves the video card in a bad state so that no X
further servers can start at all, on any VT, until a reboot. The
logfiles show that xf86() caught signal 4. (SIGILL??) Unfortunately I
don't have the original error message; when I tried to reproduce it, X
crashed horribly and locked up the entire system (not ctrl-alt-SysRq,
not even the power button which triggers shutdown via acpid, responded).

I use xdm to spawn the servers; I'm not sure if this has anything to do
with it. Downgrading to unstable (1.5.1.0-2) fixes all of these
problems.
