So on Friday I updated my ultra60 to HEAD. It had been running HEAD from
about a month ago. Today I came in and rebooted into the new kernel and now
it hangs probing uart1 off of a PUC device. Note that I do not have a
keyboard and mouse plugged into this box.
New dmesg:
KDB: stray vector interrupt 2029
