:> I also recommend using 4.2-Stable rather then 4.2-Release. 4.2-Release
:> has a number of bugs and security holes relative to stable.

:I upgraded to -Stable before sending the question, hoping that would
:solve the problem. I recall there being some strange problems with the
:ahc drivers in current about the time that 4.2-RELEASE, and thought

I dunno. I think we won't know until you manage to get the broken
into DDB. From there you should be able to do a 'trace' and a 'ps'
to hopefully see where things have locked up. If you have setup a
dump device & swap, you should also be able to 'panic' the kernel from DDB
and get a core dump.
