There are multiple things with long timeouts happening here, but it should be simple to find them. Most obvious ones are: - all disk controllers probe their devices and e.g. ATA disks have 30s timeouts for the identification. - USB devices are enumerated I would try to kill all usb controllers (e.g. via userconf or special test kernel) and see if that fixes things, or all disk controllers. Then disable individual USB devices one by one untill you have the culprit (or all disk controllers). For the USB part you also could try kernhist for options USBHIST and check vmstat output right after booting single user (or from ddb). Martin Martin
