KDB on SMP machines

[Corey Minyard]

I'm trying to get KDB working properly on an SMP machine, and it seems 
to have some problems.  There's KDB_VECTOR, which doesn't seem to be 
tied to anything but seems to be used to stop the other CPUs, 
KDBENTRY_VECTOR, which is for initial entry.  In general, the SMP code 
seems half-done in the patches on the FTP site.

kdb enters ok and I can debug on the CPU that entered KDB, but I am 
unable to switch to the other CPU and it seems to still be running.

I read some discussion on the mailing list about this, but there doesn't 
seem to be any resolution.  Is there any?

Thanks,
