I was able to copy over a GENERIC head/r280342 kernel from my build
machine to the laptop; that booted, and I was then able to do a source
"upgrade" on the laptop:

FreeBSD g1-254.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #1546  
r280342M/280343:1100066: Sun Mar 22 10:45:54 PDT 2015 
r...@g1-254.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY  i386

So I should be able to resume daily tracking of head on my laptop. :-)

(I also reviewed my kernel config file; it turns out that all of
the sound-related stuff had been commented out, so I removed all
of those lines: all other things being equal, I prefer "simpler.")

Peace,
david

Early panic at boot: exclusive sleep mutex hdac1 (HDA driver mutex) ...

[David Wolfskill]

As noted in a thread on -mobile yesterday, I'm replacing my long-serving
Dell M4400 laptop with a newer model (M4800) -- you can see -mobile
archives for additional details if you're interested.

What prompted this note was:
* When I tried to boot head/i386, I got a rather quick panic (well
  before any file systems were mounted -- and before any swap space was
  allocated, so I didn't have a place for a crash dump.

* Much to my (positive) surprise, when I looked at /var/run/dmesg.bo0t
  (after having rebooted from my stable/10 slice, and in the process
  of reviewing my kernel config to see if I could configure around
  the panic)), I found some verbose boot messages from the attempted
  boot under head.

So that latter actually provided a bit of information that might be
useful for debugging, so I copied it to
, as dmesg.boot.

Here's an excerpt from it, in case that's useful.  (I didn't want to
spam the world with the whole 74KB thing):
