Hey, absolutely!  I'm enjoying myself.  :-)

Well, I've managed to get it to die in front of me this time.
You'll have to tell me how to get it do do a backtrace -- I'm
leaving it at the debugger prompt expressly for that purpose.
Transcribed by hand below is what I see leading up to the crash.  I
was on a fresh boot trying to do a make clean under x11-wm/xfce4.  I
had built it on the previous boot and froze it remotely when I tried
to do a make clean (xfce4 works great -- no changes to the port).
Here is what I see (first two sets repeated multiple times, xxxxx
represents various lba, ad0s5 is root):

ad0: timeout waiting to issue command
ad0: error issueing WRITE_MUL command
ad0: timeout waiting to issue command

What next?  Can I even do a dump if the ata driver is the culprit?
