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
Set CONFIG_PDC202XX_FORCE on.

This works, thank you. This option didn't get my attention at first
because its named Special FastTrak Feature in xconfig. Perhaps this should
be changed.

Yes. The behaviour should be as previous kernels (work with the kernel
driver by default).
The following patch should fix it.

Yes it does. Line 410 of ide-pci.c should be changed too, from:
#else /* !CONFIG_PDC202XX_FORCE */
to
#else /* CONFIG_PDC202XX_FORCE */
