After switching consoles a couple of times, it the switch no longer
succeeded but hanged. I had to reboot. Noe that I can access the log, I
see:

Jul 25 12:58:54 babbage kernel: stuck on TLB IPI wait (CPU#0)
Jul 25 12:58:54 babbage kernel: stuck on TLB IPI wait (CPU#0)

(The show regs was issued by me although I never saw the output.) This
also shows that the clock has stopped completely, it was ~21.00 when I
pressed sysrq-p - the machine stopped responding ping at ~13.00.

Stuck on TLB IPI wait... Perhaps this is a BP6 problem after all?
