[TuxOnIce-devel] Have some (garbled) crash info for ToI 3.2 and 2.6.39.4

[Kenneth R. Crudup]

As I'd been saying, 2.6.39.1 has been rock-solid- been able to do many
cycles w/o a single hitch, but all future versions haven't been able to
resume properly, and it appears to be a BUG_ON() in the suspend phase
making the resume crash as well, so it gets to "Cleaning up" and never
finishes.

It also only appears to happen if the suspend image is large, too. Small
ones don't seem to be a problem.

I put a serial console on the box, and was able to get this much on the
suspend end. The TOI stuff garbles the output (will try it again w/o the
userui_text running) but I think it's a start:
