[Der Geist der Maschine]

Any kind of heavy use at I get these errors and it typical will lock up.  Occasionally a kernel panic.  (which sounds like Der Geist got also)
I'll see if ddb is useful on the main display or if I need to enable my serial console.

The crashing kernel was kind enough to save a stack trace in dmesg. On the following boot, it was available in the then old dmesg.

I don't recall the precise stack trace but it originated in something like idle_thread or so. The kernel crashed not under load but while doing nothing
