Something is dropping the I/O performance across multiple controllers badly
from 2.0 to 2.1. This includes IDE, AHA1542 and Buslogic scsi combinations.
It might indeed not be the locks.
For the ISA network cards its fairly obvious where the problems are and also
extremely hard to fix to get the same results as in 2.0.x (because the hardware
itself is designed to be single threaded) - but not impossible.
