As far as DEVFS goes, isn't that config option now depreciated, and everything is in devfs?
By the way, I think I see his problem right now! Exactly as I said in my last message on this topic... What does his dmesg say for
ata1? irq 15? Same shit I ran into... ata isn't reading if the controller is disabled in BIOS. Under -stable, this is being
read, and no conflict exists.
Could this actually be related to changes in ata?
SMP and ahc0/1 work fine here... Tyan S1696-DLUA MoBo, 2 P2-333's, Linksys 10/100 on dc0, DEC DEFPA SAS UTP-PMD, SB Live!, and
WinTV/Theatre.
