[Bug 554835] Re: [855GM] GPU hang when an application tries to use XVideo
I don't have the notbook with me now, but a co-worker of mine has the
same issue with identical hardware. It seems there is no problem with
this kernel: http://kernel.ubuntu.com/~kernel-
ppa/mainline/v2.6.34-rc3-lucid/ (just checked out on his notebook). It
means that for example mplayer can play videos with XVideo output
(mplayer -vo xv ...) without a crash. Also kernel package just has been
upgraded to 2.6.32-21.32. With that kernel not even login screen got
just black screen and no disk I/O after a while ... (even with boot
options nosplash - btw even with noplash there is splash -, and quiet
option is removed too). According to /var/log/kern.log the kernel log
ends at the MTRR stuffs in the "middle of a line" and logs of the new
boot (with that 2.6.34 kernel which works) starts with the date/time not
at a new line ... xorg.log files in /var/log/ does not give many
informations the only difference some kind of acpi socket opening
problems.
