>Description:
The `mach cpu N' command in ddb lets you switch to another CPU's saved registers and stack, even if the CPU is running and they haven't been saved into the lwp state. crash(8) is built without support for `mach cpu N', though.
>How-To-Repeat:
Try to examine another running CPU's registers and stack trace in a crash dump.
>Fix:
Yes, please!
