OK, here is the interesting part of the trace.
Thanks for the decode...
Up to this point, something hits the UPS with control messages every
4ms
(sounds crazy, but here it is: the daemon is obviously out of
control).
That is insane. No wonder the thing locks up eventually.
Christian, back in mid-May I suggested a way you might be able to
reproduce the lockup faster:

You're not still running with that change, are you? It would certainly
account for why the UPS is getting blasted with control transfers. But I
don't think this is the case since we'd see them in the HID debug
output.
Something else to try: Turn on the usbfs_snoop module parameter for
usbcore.ko. The system log will then show if any processes are using
usbfs to communicate with the UPS.

Here another one, btw I did pass usbfs_snoop on to the kernel during
boot, but have no entries in my logfile. Hmmm, usbcore is not a module
so usbcore.usbfs_snoop=1 should have done the job isn't it??? Currently
my apcupsd is hanging in state 'D' again ;-) whats next? FYI, I have
removed all previous patches given for testing.
