Last I checked, the scheduler isn't really involved with interrupt
requests.

Really, it's more likely to be a hardware problem, as the thread on this 
last week mentioned in wonderful poetic form, or a problem with the ide 
driver in use.

The "preemptive scheduling makes it so hard to do realtime tasks" argument 
for CDs was really great with 486 hardware, but really, we're talking 
about ~8MB/s here.
