OK, willdo.

I had another occurrence of this last night, with a
not-very-plausible-looking stack trace. I captured it with my digital
camera and here it is retyped (timestamps omitted, and wrap damage fixed):

Process cat (pid: 2464, ti=f46f4000 task=f6104000 task.ti=f46f6000)

In case it's at all relevant, a copy of cat running on this machine is
quite likely to have been reading or writing a pty with a SLIP line
