Still not fixed. As I mentioned, the revert of
5c12a07e8073295ce8b57a822f811ac34e4f8420 missed some lines. I'm not familiar
with the hardware or the code, so I'm not sure if this patch is right. At least
it solves the bug for me. Chris any objection to re-adding it?

Still present in 2.6.37-rc4. The box with the problem has been repaired and I
can now debug the problem again. Any hints would be appreciated.

Do you know the change that fixed it or you just can't reproduce it any more?

git bisect identified
[305e6835e05513406fa12820e40e4a8ecb63743c] sched: Do not account irq time to current task
as the cause of this regression. Reverting it from 2.6.37-rc4 (requires some
hackery due to subsequent changes in the same area) restores sane behaviour.
(Author of original patch cc:d.)
The original patch submission talks about irq-heavy scenarios. My case is the
exact opposite: UP, !PREEMPT, NO_HZ, very low irq rate, essentially 100% CPU
bound in userspace but expected to schedule quickly when needed (e.g. running
top or ps or just hitting CR in one shell while another runs a compile job).

Thanks, added the first bad commit information to the bug entry.
