I went back and looked and the ACPI issue I saw was actually a power
down, not a reboot. ACPI was receiving one of the S states (S3 I
believe) because of a hardware bug.

You mentioned ipmi, have you looked at ipmi logs?

In another unlikely case, I had a motherboard which would cause panics
because the clock on the memory needed to slow down. I think randomly
it would just reboot without a panic, but memory issues usually cause
panics as you pointed out.
