I'd like to check out 2.4.4 as well -- installed 2.4.2 XFS 1.0 a couple of
days ago, and I'd like to say "good work, give yourself a collective pat
on the back" ;-)

Unfortunately, my system has a VIA Apollo Pro chip set, which isn't 100%
happy with 2.4.2 (none of the UDMA modes above 2 seem to work, e.g, and
you get fairly poor perfomance by the looks of it).
Gather 2.4.4 has some fixes for Via Crapollo... how would I go about
downloading 2.4.4 XFS?

I installed 2.4.2 XFS on a 20GB Seagate IDE disk (5,400 rpm, 512KB cache,
ATA-66) as well as a pair of IBM SCSI disks (7,200 rpm, 512KB cache, FW
SCSI 40MBps).

This is probably a Linux issue, but when I boot up from the IDE drive, and
do hdparm -tT, I see 78/15-16MBps results; however, if I boot up from the
SCSI drives, I see 88/9MBps for both the SCSI and the IDE drives. Can't
explain this, unless hdparm is giving some completely bogus results.
