After the request for more testers (after a backup) I d/l'ed and
compiled 2.5.39. My setup isn't trivial, but should be fine for 2.6; SiS
chipset, athlon 1gzH, 512Mem, pci promis ide controler, softraid 0 and
5. This is a gentoo install that loves devfs for some reason (I've
always found the paths to be overly long.)

Anyway, right after partition detection ide-scsi detection of my old
no-brand cdrw drive and dvd drive triped this (written down):"
