James,
I just tested it in lk 2.6.7-bk2 and the advansys driver is
broken. The disk access light stays on for several seconds
while it tries to read the partition table after which it
announces "unknown partition table". Since my rootfs is on
that disk it's all downhill from there.

HBA is a ASB3940U2VV (PCI) and it worked ok in lk 2.6.6 .
I haven't tried lk 2.6.7 (release yet).


Also when I put an ISA Advansys HBA in the box (with the PCI
advansys HBA) it causes an oops during bootup in
AscInitGetConfig+0x75/0x1d0
which is called from advansys_detect().
I think this ISA HBA has been causing this oops each
time I have tried it in the lk 2.6 series (not just
with lk 2.6.7-bk2).
