I tried switching one machine here from old IDE
modules to a new pata subsystem today. And it
failed, for the first time I ever tried this
procedure. Pata_via refuses to recognize one
of the drives.
Here's the dmesg with via82cxxx (2.6.20):

(yes, the second IDE cable isn't UDMA one).
And here's the same when booted with pata_via module. 2.6.20
and 2.6.23 behaves the same way:

That's it - no sdb (or should it be sdc?) detected, only sda.
Any ideas?
Thanks.
P.S. By the way, there are two lists - linux-ide@ and linux-scsi@.
Which one should be used to discuss pata- (and sata-) related stuff
like this?
