Could you try to test the attachment patch and see if it can fix
your problem?
If you can confirm the patch may fix the problem, we will add the
pci device id(0x1c01) into the quirk patch, which has been submitted into
kernel maillist before[1] and will enter Oneiric.
BTW: the bug is very similar with 794642, and both are using
sandybridge chipsets.
