SubjectRe: GPU hung with Linux-3.2-rc6

It would also be nice to know if disabling VT-d in the BIOS resolves
this issue, or if building the kernel with IOMMU support and then
forcibly disabling it with 'intel_iommu=off' fixes the problem. Given
that you can easily reproduce this, it would be good to know how your
machine differs from dozens of others which work fine with semaphores
turned on...

Oh, and the output of 'lspci -nn -vv' would be nice to see in case
you've got older (or newer) chips...
