SubjectRe: AMD64 X2 lost ticks on PM timer

In case you are coming late to the thread:

The lost ticks are closely correlated with sata_nv disk activity on
multiple disks, and the problem is easily reproducable with "find /usr |
cpio -o >/dev/null" on an MD RAID1 -- but not on a single disk.
Andi suggested:

Yes, I bet something forgets to turn on interrupts again and it's
picked up by (and blamed on) the next guy who does an unconditional
sti, which happens to be __do_sofitrq or idle.

That sounds right to me.

I built 2.6.16-rc5-git6 yesterday, and it still suffers from the same
issue.
