Subject2.4.14-16: Can't see hdb or hdc on ABIT BP6
Greetings,

First, please CC me in replies, as I'm not subscribed...

I have an ABIT BP6 dual-Celeron system, with six IDE drives, four on the
PIIX4 controller and two on the HPT366. For some reason, Debian
kernel-image-2.4.14-686-smp and 2.4.16 can never see anything on hdb or
hdc, but have no trouble at all with hda, hdd, hdf or hdg. It's as if I
removed those two drives. The corresponding Debian 2.4.9 kernel package
always works perfectly, as does 2.2.19 and various other 2.2 and 2.4
kernels leading up to those.

I originally thought it was an ext2 problem because fsck couldn't mount
hdb1 or hdc1, and that's where the boot process would stop. The Debian
slink install made hda1 (root) without sparse superblocks, and hdb1
(/usr) and hdc1 (/var) with sparse superblocks, making that the
suspect. But then tune2fs wasn't finding the partitions either, and
raidstart was finding hda3 and hdd1 but not hdb3 or hdc3 (which are 10
GB each making up a 30 GB RAID5 array), and also could find hda2 but not
hdb2 or hdc2 (for a RAID0 array). It was finding hdf1 and hdg1 just
fine for another RAID0 array.

So it's as if hdb and hdc are not there!

For more info on those drives, I've attached the relevant boot log
portion from /var/log/messages under 2.4.9. Since the missing drives
are identical to hda, which works just fine, I'm mystified...

I would much appreciate any insights/solutions, and am happy to provide
additional information toward that end.

Thanks,
