[i945gm] Graphic accelleration randomly not working with Karmic: drm Cannot initialize the agpgart module

[Pascal R.]

Binary package hint: xorg

at circa every third boot on my ThinkPad T61 with i945GM chipset, the graphic acceleration is not working. I can see a short flash of some message with "[drm] *ERROR*" in it before usplash starts. If the error occures /var/log/dmesg contains this:

$ cat /var/log/dmesg.0 |grep drm
[ 1.844923] [drm] Initialized drm 1.1.0 20060810
[ 2.092935] [drm:drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
[ 2.093008] [drm:intelfb_restore] *ERROR* Failed to restore crtc configuration: -22

if the error did not occur, it looks like this:

$ cat /var/log/dmesg |grep drm
[ 1.876103] [drm] Initialized drm 1.1.0 20060810
[ 2.699884] [drm] fb0: inteldrmfb frame buffer device
[ 2.704187] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0
[ 3.058291] [drm] LVDS-8: set mode 1024x768 c

after the errorenous boot, the Kubuntu desktop effects are disabled and cannot be enabled. Also the system is very slow. That is the reason I reported this bug with "ubuntu-bug xorg" after a normal boot process. Should I take the time to do the report again after a boot process with errors?

seems to be gone. Had no problems for a while maybe since kernel 2.6.31-14
