2.6 does more (perhaps excessive in some cases) checks. There's a
background polling timer that kicks in every 5 seconds that looks at the
machine check exception registers to see if anything nasty happened.

In an ideal world, MCEs only get raised when bad hardware misbehaves
(ie, due to overclocking, bad cooling etc). However they can also be
triggered through device drivers doing bad things. What other hardware
is in the box (or rather, what drivers are in use) ?

There are also some circumstances where it picks up false positives
(usually during suspend/resume, or some other BIOS-involved task).
