Poudriere bulk results, reviewed after the incident

(In reply to Graham Perrin ◐ from comment #6)

> … I guess, symptoms might be quite different with GENERIC-NODEBUG.

Before the 06:37 BOOT below I found a blackout, no response to HID input. 

Presses on the power button produced slight reactions (a flickering LED, not
for long, at the front of the HP EliteBook 8570p) but not the expected shut
down. A forced stop (press and hold) was required :-(

From the attached screenshot, I assume that system failure occurred some time
after 02:29. 

I uploaded the result of a probe not long after the boot, I expect this to
automatically appear at <https://bsd-hardware.info/?computer=6fbb1f806232> in
due course.
