Okay, I spoke too soon. bluetooth & suspend memory corruption was
_way_ harder to reproduce than expected. Took me 5-or-so-suspend
cycles... so it is probably unrelated to the previous crash.
I was getting pretty regular crashes with bluetooth & gdb, but I was
not using bluetooth at the time of ext3-related crash.
