I am seeing an intermittent failures to detect sata disks on
2.6.18-rc2. Dell SC1425, PIIX chipset, gcc 4.1.0 (opensuse 10.1).
Sometimes it will detect both disks, sometimes only one, sometimes none
at all. AFAICT it only occurs after a soft reboot, and possibly only
after an emergency reboot. Alas the problem is so intermittent that it
is hard to tell what conditions will trigger it.
Setting ATA_DEBUG gives these differences:
