Just to save other folks' time, I'd like to remind that using
Ctrl+Alt+Esc to escape to ddb still leads to the system freezing
hard if kbdmux is enabled--at least with a PS/2 keyboard. I had
missed this issue when it was brought up here a month ago, so I
spent some time to find why my system was hanging dead. Possible
workarounds found:
- remove kbdmux from the kernel configuration file
- disable kbdmux in device.hints:
hint.kbdmux.0.disabled="1"
- go straight to remote gdb:
sysctl debug.kdb.current=gdb
sysctl debug.kdb.enter=1
