[Bug 509273] Re: [Lucid] Radeon Xpress 200M needs PCI quirk to fix or disable MSI

[gene]

Hi all,
Sorry got lost. The launchpad is such a bliss: you can leave a comment and the system won't find where you did it, unless you subscribe.

2 Lollerke: the radeon.modeset option was not a default for some time
(in karmic at least) maybe because to the kms issues, please see the my
related bug.

Got another crash. This time, I have some entries in the logs. Not much but this is something. TO make it more readable i'll use this 
grep drm -A2 -B2  /var/log/kern.lo

The crash happened around 20:47. This was the last entry for the session
(lasted about 20 hours). To get out I used the Raising-Elephants-Is-So-
Utterly-Boring incantation.

Again, in my case kms is useless and dangerous. I cannot fully utilize
it, because, 1) suspend won't work, 2) it gie plenty of video issues,
like more cpu time and results in lower xvid quality when playing videos
even with mplayer.

I would like to know to turn the kms off? I did try radeon.modest=0 - I still get nice tty fonts. However, I see this 
May  4 20:52:28 jenshen kernel: [    2.238430] [drm] radeon defaulting to kernel modesetting.
May  4 20:52:28 jenshen kernel: [    2.238437] [drm] radeon kernel modesetting enabled.

I will double check.
