I noticed on reboot last night that it was complaining about reiserfs.ko
and reiser4.ko.  I was not able to catch the entire message as it
scrolled by.  But it appeared to not be properly implemented in my
running kernel.

Question:
Is there an issue with having bother reiserfs and reiser4 in the same
kernel?

Subject: 9.3 Slow I/O on RAID0 SATA

I just installed 9.3 (64bit) last night on an MSI K8N NEO2 Platinum
mother board with an Rev E 939 3200+ chip currently over clocked from
2.0 GHz to 2.4 GHz, 1 GB of OCZ Platinum (2-3-2-5) Dual Channel RAM and
2 Seagate 160GB SATA drives in a RAID0 (striped). 

Well, not fully striped, /boot is mirrored, then 1.3GB on each for swap
(un mirrored) and then the rest of the disks are stripped for /.

I have horrible I/O latency.  Running the top command shows my I/O wait
to be around 89%.

I had this system running 9.2 (64bit) on a stand alone PATA Seagate
drive and it was amazingly fast.  So I'm going to assume that I can rule
out the over clocking and focus on the I/O and the OS.

This is a fresh install of 9.3, not an upgrade from 9.2.  DMA is enabled
in the BIOS for the SATA drives.  I did not see the drives listed under
YAST2 for the IDE section to turn on DMA.

Does the above listed disk layout (Mirrored/jbod/striped) on the same
disk seam acceptable?

Where else should I start looking?
