I have been using the 3.2.0-26.41 kernel for over a day now and do not
experience momentary system freezes anymore. Previously they were
happening pretty often and sometimes compixz/Unity could not recover.
The new kernel appaers to fix this issue.

Andy: could you test something simple.. to disable FBC you can give an
option to the kernel 'i915.i915_enable_fbc=0' by editing the kernel
options from the boot menu. So if could test with that when booting the
-25 kernel it would be great.
There is a commit in upstream v3.2 stable queue
@Timo Aaltonen (tjaalton)
added 'i915.i915_enable_fbc=0' to kernel params and it fixed the issue totally!

@kernel team - upstream says framebuffer compression should be disabled
for sandybridge as an interim fix to this and other similar issues.
This was disabled in 3.3-rc4 due to BLT ring problems and performance
