Update - the panics are uvm_fault panics. Not sure what's up, but:Why don't you post dmesg and backtrace?
I have to bring a serial cable and USB-serial to get all of that - it's physically in an awkward place, so typing everything manually would be pretty hard.
5.0.1 seems working on LC630 (at least on single user):
Single user mode seems to work fine, as does the installation kernel, but trying to boot multiuser doesn't.
Thanks, John
