Volker & Kris,
Sorry for kind of hi-jacking your thread. Just hopefully we all can work
together to fix this issue (if there is one).
For me, that's ok as it may (or may not) be a similar problem.
Out machine did goto in to a "hard lock". Nothing showed up on the screen or
logs.
I did see something from WITNESS in dmesg. See below. But this does not show
up at the time of the crash. If I remember correctly this show up at boot
time.
We have added the following kernel options:
options DDB
options KDB
options BREAK_TO_DEBUGGER
options INVARIANTS
options INVARIANTS_SUPPORT
options WITNESS
options DEBUG_VFS_LOCKS
options DEBUG_MEMGUARD

----------------
From this output, I would assume, we're fighting with two
completely different problems. I've catched 3 LORs and a strange (?)
ACPI message within the last few hours.
I'll post everything I've got in another post in a few minutes.
Volker
