When I disabled passive cooling (and reduced my frequency to prevent overheating), the system was stable. I've since read the handbook about ACPI and added the mentioned hint to disable APIC (though I don't even have apic in the kernel?). Hopefully that fixes these mysterious hangs. The panic I saw may have just been a coincidence. Best Regards, Nathan Lay
