Does your motherboard have a Promise FastTrak on it? If so this is a bug I
reported in 2.4.3-ac10/11 and that Alan Cox fixed in -ac12 - for some
reason it didn't make it into 2.4.4. I was just about to report it myself
when I saw your mail. The following patch fixes:

--- ide-pci.c.orig	Sun Apr 29 12:41:05 2001
