Cool -- and I'll proceed with building & smoke-testing, as usual. :-)
(Next attempt: tomorrow morning.)

And yeah -- stuff happens; we're (each) human.  :-)

In that revision I neglected to zero the "first" field of the unrhdr.
Sorry about that. I also inadvertently wasn't testing with DIAGNOSTIC
on. I will commit a fix.

OK; I believe we have a winner!  Thanks! :-)

I copied the head slice from slice 4 to slice 3, used

svn merge -c -r324542 ^/head

to revert the commit, then booted from slice 3, re-built & installed
the kernel.

For *that* reboot, I (again) had the screen go dark & unresponsive;
typing "reset" (blindly) brought the machine back up.  (The file
systems had been unmounted cleanly before the panicearlier.)

I then rebooted again (now that the new kernel was in place), and there
was no issue -- the laptop rebooted normally.

Thanks again!

Peace,
david

Will do; but I have a few things to get done first, so it may be an hour
or so before I can report results.

Until ... recently, eh?  :-)
