I just tried booting off the FreeBSD 5.2 install disc on my system. No crash on removal, but I do get the same three repeating error messages and still no device appears in /dev. Then I tried this boot disc on an Intel (440BX) machine. No error messages, but still no /dev entry. I must be seeing both an old VIA-related 4.X bug and a newer 5.X bug where the device doesn't appear, which recently can also trigger a crash. Did you say that you can mount the filesystem, and it freezes when you unmount it? What happens if you just unplug the device after plugging it in? I don't have a way to mount it, but unplugging the device crashes my system.Received on Sat May 29 2004 - 22:01:53 UTC
