I was just trying to build lang/perl5 (dependency of many packages) and
it hung.  At least this time there were some console messages:

  trap: pid 1334.1 (try): user ISI trap @ 0 (SRR1=0x4000d032)
  trap: pid 12358.1 (try): user DSI trap @ 0x25732560 by 0xefeeefc4 (DSISR 
0x40000000, err=14)

I can't really say if or how closely related the events are and the pids
are inscrutable since the machine is unresponsive.  The last thing the
perl build displayed was:

  [...]
  Writing Makefile for Switch
  [hung]

The terminal driver is still accepting/echoing characters and wscons
lets me switch terminals, but that's it.
