My understanding of the problem is incomplete, but I'll throw my information in the pot and say I often see this sort of error during boot, and sometimes the system recovers and continues, and othertimes it locks up before the login prompt appears and I have to reboot and try again. Also, the problem seems to happen more often with the 2.2.17pre5 kernel I got out of frozen than the old 2.2.15pre? kernel that was originally packaged in frozen... -raf
