 Does 3.2 work on the T420? Is it a graphical thing - can I disable
 it with a kernel parameter?

It looks like T420s has the same graphics as T520 (Intel HD 3000). I had
a problem with this GPU and R3.2 (random reboots) and I have solved it
by adding i915.enable_rc6=0 to kernel parameters:

BTW with iommu=no-igfx my T520 didn't boot at all.
