I have had 100% success. I'm using 2.2.5 kernel without any tweaks,
straight out of box. I have two disks attatched without cdroms,
tapedrives or such. Motherboard is some recent Compaq (don't remeber
which). The machine has now been running for a week in production
environment without problems. I have done some quite heavy I/O
operations that have thoroughly exercised the disk subsystem.
