Sometimes I disable all uhci, ehci, xhci to get activity in ddb based on
PS/2 emulation. I think it worked once...

sysctl -w ddb.onpanic=0 will dump core, which is probably preferable.
And if it fails, it's sometimes visible in dmesg scrollback.

What's the panic reason?
Do you have a netbsd.gdb for line numbers (especially of the last part)?

Thanks,
