I'm currently reviewing the x86 2.6.27 patch /wrt to potential SMP
issues. One thing I came across is our old friend, the MTRR subsystem.
There are a few local_irq_disable_hw spots, some are even
local_irq_disable_full, but others are still plain vanilla, and I'm not
100% sure that this is correct. I will check this carefully, probably
coming up with some correction patch.

In the meantime, could you check if disabling CONFIG_MTRR changes the
picture you (or anyone else with a similar problem)?
