sky2: hung mac

[Knut Petersen]

I got a sky2 "hung mac" message.

grep-ing the logs I realized that this already happened
 two times, but that was about 8 months ago.

system hw: AOpen i915GMm-hfs, Pentium M Dothan 2GB,
                    2 Yukon-2 EC chips, revision 1.
system sw: oct: kernel 3.1.0, running since oct 24.
system sw: oct: latest stable kernel at that time
system is always on.

Is it a sign of a bug or should it simply be ignored?
