I have an IBM 10.1G UDMA drive. I'm using it with a Tyan dual PPro motherboard - it's an S1668, upgraded with the latest (May 1998) bios.
The odd thing is that the kernel will only talk to the drive in UDMA mode if I have my old Western Digital 1.6G disk plugged in on the secondary controller. Since I'm giving that disk away, this is a small concern. (It's only a small concern since linux is installed primarily on SCSI disks attached to the same system.)
Here are the relevant bits of a boot where the kernel isn't happy with the drive:

Like I said - this doesn't happen if I install my Western Digital AC31600 to the secondary controller. Then I don't het the timeout message, and hdparm says it's talking to the drive using UDMA.
Thanks for any hints.
