Hi

Kernel 2.4.19-rc3 introduces a new bug regarding the Promise PDC20276
controller. One of my machines has a Gigabyte GA-8IRXP Motherboard with an
onboard Promise PDC20276. The controller can either be run in RAID or in
ATA mode. I operate it in ATA mode. Kernel 2.4.19-rc3 now incorrectly
skips IDE initialization of the PDC20276 because it thinks it's a RAID
controller which results in a kernel panic (the root filesystem is on a
harddisk connected to the Promise controller). It outputs a message like
this before it panics: PDC20276: Skipping RAID controller. This worked
correctly in 2.4.19-rc2.

Regards
Daniel
