dmesg output

I apologize if I post this in wrong section. 

I'm a problem with all distro with kernel 2.6.35. On boot I receive this error:

[   10.355659] [drm:init_ring_common] *ERROR* render ring head not reset to
zero ctl 00000000 head 02001000 tail 00000000 start 02001000
[   10.355725] [drm:init_ring_common] *ERROR* render ring head forced to zero
ctl 00000000 head 00000000 tail 00000000 start 02001000

When I use the system, mouse and keyboard "randomly freeze" and go very very
slow for a short time (5-6 seconds). Is extremely annoying.:D

I've tried with many distro like Ubuntu 10.10, Debian Sid, OpenSuse and more.
Results are the same.

I attach complete dmesg log and all my hardware info.

I hope to be useful.
