Just wanted to chime in with a FWIW post :)
I've also got a Promise PDC 20262 w/ an IBM Deskstar running in UDMA
mode 4 w/ no problems whatsoever. Additionally a Maxtor Diamond Max
connected to the stock BX MB w/ no problems. Early on (5-6 months ago) I
did experience some minor corruption problems with the Maxtor connected
directly to the mainboard, but never anything with the IBM on the
Promise card. That thing's been solid. All fs's are XFS except boot
which is reiserfs.

Strange. I'm experiencing the same problem on a Promise PDC20262
controller card too!
Another thing, is that I've never, well... mostly never ;) ,
experienced problems with other filesystems
on either chipset (I know there are issues with the VIA stuff, had
problems with the USB stuff too,
makes me wonder why I bought the MB in the first place...)
Anyway, I'm gonna try and use a different drive and see if I
experience the same problems. Using a seperate
partition, mounted on my ext2 root, I haven't been able to make it
fail. Gonna install RH 71 on the XFS
partition and make it a root, and see if it'll fail there (as it does
on my Fujitsu drive)

That's what we've got in common -- the VIA chip set. Nothing but trouble
with that, to be honest. Memory performance is slower than on 440BX chip
sets (trying to work out how to tweak the PCI registers with setpci
so as to
enable memory interleaving) and the IDE interface works poorly.
Also discovered that there's an issue with the IO-APIC and Linux. If I
disable it (append="noapic" in lilo.conf or at the boot prompt), I
the weird slowdown in disk performance.
