Bug description: With KMS enabled, I can only resume from suspend to ram (using pm-suspend) once. After the second suspend, the system does not resume but instead reboots as if the system had been powered down (I have the BIOS POST screen, etc).
-- chipset: 945GM
-- system architecture: 32-bit
-- xf86-video-intel: 2.9.1
-- xserver: 1.7.4
-- mesa: 7.6.1
-- libdrm: 2.4.17
-- kernel: 2.6.32-trunk-686 (Debian unstable)
-- Linux distribution: Debian squeeze/sid
-- Machine or mobo model: Dell Latitude D420
-- Display connector: internal LCD
Reproducing steps: this bug is reproducible, simply by invoking pm-suspend or hitting the sleep button twice.
Additional info: also observed with Debian kernel 2.6.30-2-686.

dmesg output with boot option drm.debug=0x06
Obviously this is taken before the second suspend.

Does this still happen with 2.6.33 or more recent?
I have reenabled KMS and the bug does not seem to be there anymore with kernel package 2.6.33-1~experimental.4 from Debian experimental nor with 2.6.32-11 from unstable. What else has changed in the meantime :
-- xserver: 1.7.6
-- mesa: 7.7.1
-- libdrm: 2.4.18
So everything looks fine now. Thanks !
Thanks for the update!
