8.0 machine won't boot single user

[Matt Burke]

I have a server (Dell 2950) running 8.0-RELEASE-p1 that won't boot into
single user mode - it hangs on "Trying to mount root from
ufs:/dev/label/root". It hangs when using the /dev/mfid1s1a device too so
it doesn't appear to be a glabel issue.

Previously I had this issue booting multi-user too and the only way I could
fix it was to reinstall the base distribution from CD, but this time it
appears limited to single user mode. Normal boots work fine.

I have built a kernel with DDB to get a backtrace, but hitting ctrl-alt-esc
causes the USB keyboard to die. The machine has no PS/2 ports. After the
kernel initialises the NICs, the IPMI serial-over-lan dies, presumably
until rc brings the interfaces up, so I can't fire up DDB over the serial
console. Setting hint.bce.N.disabled=1 at the loader prompt doesn't prevent
the kernel from initialising the NICs. I don't have another machine with a
physical serial port.

Is there anything I can do to diagnose+fix this issue short of trying to
hack sys/dev/if_bce.c to bring the interfaces up on attach?


Thanks
