Looks like the relevant messages are still DRM_DEBUG in 2.6.32-rc8, so I uploaded a debug-enabled kernel log to http://people.freedesktop.org/~jcristau/25371/kern.log-debug (it's too big for bugzilla). Jesse mentioned lowering srwm and plane[ab]_wm by a few entries, I haven't tried that yet. I can do that tomorrow (UTC+1) if necessary. Possibly related is that after some time the screen seems to get stuck with a solid color. This happened twice, right now it's purple. Apps (and X) still run fine, apparently, but I wasn't able to get anything back on the screen (only managed to get a black screen with xset dpms force on/off). fwiw i915.powersave=0 seems to work around this. Does this still happen with 2.6.33-rc? If so, does David John's patch fix things? http://patchwork.kernel.org/patch/75423/ > --- Comment #3 from Jesse Barnes <jbarnes@virtuousgeek.org> 2010-02-05 15:14:25 PST ---

Testing 2.6.33-rc7 now. I guess I'll know by tomorrow whether this is
fixed.

at least the flickering is still there with rc7. testing with your
'drm/i915: handle FBC and self-refresh better' patch now.

Created attachment 31618 [details] kernel log As mentioned on irc, after upgrading from 2.6.31 to 2.6.32-rc8, my panel started blinking for a fraction of a second from time to time (on the first boot it seemed to be pretty regular, every 20s or so, now it seems more random). This is with xf86-video-intel 2.9.1, xserver 1.7.2 rc2, libdrm 2.4.14. kernel log with drm.debug=0x6 attached, doesn't seem to have much info though.
