the params that Steve as referring to is in the last structure defined
in
elevator.h
8192, /* read passovers */ \
16384, /* write passovers */ \
Bumping these number down helps the problem, but doesn't fix it.
(they start out at 1 million and 2 million)
I'm working with a patch from Jens Axboe that clean up the
elevator quite a bit. Unfortunately the system will panic
when kiobuf io is used. I'm working on tracking down the problem.

Please let us know if it does happen, we won't be able to track the
problem
down it if we don't know about it. We all want to see this thing
stabilize.
