Don't panic
Today I was building a new monster FreeBSD 4.10 server with PAE enabled. Booting the new kernel I got this little gem of a prompt:
The normal boot messages, and then…AP #3 (PHY# 7) failed! panic y/n? [y] _
I tried ‘n’, but unfortunately the kernel was in
no state to accept input from the keyboard. One must wonder why it even
bothered asking whether it should panic then.
