Hello.

i just attempted to test .20-rc3-git4 on a box, which has 6 drives in
raid5. it uses raid autodetection, and 2 ide controllers (via and
promise 20269).

there are two problems.

first, and most importantly, it doesent autodetect, i attempted with
both the old ide drivers, and the new pata on libata drivers, the drives
appears to be found, but the raid autoassembling just doesent happen.

this is .17, which works:

this is .20-rc3-git4 which doesent work, in pata-on-libata mode:
http://sh.nu/p/8000

this is .20-rc3-git4 which doesent work, in old ide mode:
http://sh.nu/p/8002

For some reason IDE disk driver is not claiming IDE devices.

Could you please double check that IDE disk driver is built-in
(CONFIG_BLK_DEV_IDEDISK=y in the kernel configuration)
and not compiled as module?
