I'm doing some real-time bit-twiddling in a driver, using the TSC to
measure out delays on the order of hundreds of nanoseconds. Because I
want an upper limit on the delay, I disable interrupts around it.

Nope, that sounds just about right. Buggy BIOSes

At what point are you seeing these delays? During early boot or after
boot?
It can be SMI happening in the platform. Typically BIOS uses some SMI
polling
to handle some devices during early boot. Though 500 microseconds sounds
a
bit too high.

It can be SMI happening in the platform. Typically BIOS uses some SMI
polling
to handle some devices during early boot. Though 500 microseconds sounds

bit too high.
