The machine boots up fine. Thats to be expected, the wd driver doesn't use config_intrhook_establish() to hook in the probes when interrupts should be running. From your previous mail it looked like you had both ATA & SCSI in there, then tried without SCSI and it kindof worked. The error 6 problem has been up here before, but I dont remember the solution off hand, but you should use /dev/ad* entries in you fstab, and have MAKEDEV'd them fairly resently, new bootblocks and loader are also a must. My best guess is that config_intrhook_establish() screws up something when more than one consumer uses it to hook into the boot process... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
