Comment (by Habbie):
tl;dr: disabling ACPI did not help. disabling SMP did help. Failed to
reproduce the issue in AMD-V/KVM for unrelated reasons.
I have two machines that suffer from random reboots. Running -j20 builds
makes this happen more often.
The machines are https://www.parkytowers.me.uk/thin/hp/t520/ and
https://www.parkytowers.me.uk/thin/hp/t620/ ;(the quadcore model), so AMD
GX-212JC and AMD GX-415GA.
I have tried the following (all with failsafe video on, because otherwise
Haiku does not boot at all):
* disabling ACPI - depending on reboot/powercycle sequence, this either
does not boot at all (with weird memory corruption it appears), or when it
does boot, the reboots still happen
* disabling SMP - this works, systems are stable
* running in KVM with AMD-V on Linux - within an hour, graphics stop
working, so I don't have any useful data from this experiment. I might
redo it later with a shell on serial, or via sshd.
This is on beta4, with and without a kernel update shipped somewhere in
the last two weeks.
I hope to connect serial soon, but I understand we're not optimistic about
learning anything there.
