confirmed on my machine that the issue is with r8192se by
modprobe -r r8192se_pci
after this powertop fails to trigger the kernel panic.
reloading the module gives the old, crashy behaviour.

tried with the new driver version and the problem is still there! at
least I think so -- it's hard form e to remove all traces of my old
dkms build system. goign to try that again now. I
think an upstream bug report is in order but I can't figure out where
to do that, if anyone has any clues i'd appreciate it. Also probably
if the powertop people could tell us what powertop is doing, it might
be possible to stop the system from spontaneously probing (I imagine
it has something to do with power management) and causing the crash
unexpectedly.
