FreeBSD unstable on Dell 1750 using SMP?

[Rutger Bevaart]

We have a Dell 2850 running 5.3 which has exactly the same symptom,
although a lot less frequently. It has two intel embedded NICs (em driver)
as opposed to the Broadcoms (bge). Another 1750 we have runs 4.11 and also
reboots automatically every few days.

Could it be a bug in ACPI or something?

Would be happy if some rc.conf option enabled dumping of a crash.log if
somebody would be kind enough to do an educated analysis of it :-)

Regards
Rutger
