Bug#503544: ath5k: after suspend to RAM, requires cold boot to work again

[Zack Weinberg <zackw@panix.com>]

This is just to say that after an interval of working well, my ath5k
is now completely nonfunctional in both 2.6.28 and 2.6.29.  (I'm going
to try backing all the way down to 2.6.27 next.)  Cold boot doesn't
help.  Rebooting into Windows doesn't help (it used to).   This isn't
a hardware failure, because the wireless *does* work when Windows is
the active operating system -- but the adapter seems permanently stuck
in "noise floor calibration timeout" land with the Linux drivers.
