Any ideas about this? (i915 caused kernel oops while suspending to RAM)

[Łukasz Maśko]

Today _twice_ I got such kernel oops while suspending my laptop to RAM:

It says (or at leas it seems so) that it was the i915 graphics drm module 
which caused it. My machine has i945GM graphics chipset. Currently I'm 
running xserver 1.10.0 and intel driver 2.14.0. Both of these oopses 
happened with 2.6.37.4 kernel, which I've been using since Saturday. There 
were no such problems with earlier kernels.

Has anyone else came across such problem?
