Hi folks. I was unfortunate enough to encounter a kernel trap in single user mode yesterday when upgrading from 7.1-RC1 to -RC2 using the typical build/install world. I'm still not sure what caused the trap, as the system was rebooting when I saw the screen. As one would expect, this led to an irrecoverable system; the system would automatically drop me into single user mode, as it could only mount the root directory; /bin/sh and /bin/csh would not work (had to use /restore/csh for the minimal digging I actually could do). So, now to the question. Given I could not mount anything other than /, would there have been any way for me to gather debugging information on what caused this failure? (FWIW, I am certain it is not a hardware failure.) Regards, -- Glen Barber
