outdated, this should be fixed in 2.6.32-3-686 linux images
which you can find in unstable, installs just fine in testing.

thanks for feedback.

Hello,

I am experiencing the same problem in 2.6.32-5-686 and 2.6.34-1-686 on my Acer laptop with i855 chipset. System freezes randomly as described by Eric. I guess that 2.6.32-3-686 was fine, but I am not sure (have not this kernel anymore).

Thanks,
Zbynek

Sorry for the long silence. I wonder if this was fixed by
v2.6.32.16~48 (drm/i915: Rebind bo if currently bound with incorrect
alignment, 2010-05-27) which was part of version 2.6.32-16 of Debian's
kernel packages, or one of the many other i915 fixes in squeeze.

Do you still experience this bug? What kernel version do you use?

Thanks,
Jonathan

dear Jonathan,

I'm now running a much more recent version of the kernel and
don't have this problem anymore.

thanks,
eric
