Jan, see if you can get kernel core out of it. You may have to
set sysctl kern.sync_on_panic=0, but then ctl-alt-esc'ing into
the debugger (when the machine is in this locked up state) and
typing 'panic' <return> (probably <return> a second time) should
do it if you have the dumpdev set.
I'm sorry, I'm blind. I completely missed the sync_on_panic part, I'm
redoing it now, with sync_on_panic=0.
I'm assuming the core file'll be too big to attach in a mail, so I'll
get back to you with an URL you can download it from, unless you've got
an FTP server I should upload to?
