Thanks, Sergei.  Weird --- so this means

	2.6.32-31:	intermittent reboots on resume
	3.0.0-1 (?):	intermittent reboots on resume, unless
			module unload workaround applied
	3.0.0-5:	no problem

There were some ath9k fixes in the 3.0.y stable series, but it's not
obvious which would have cured these symptoms.  The most dramatic
change (ath9k: skip ->config_pci_powersave() if PCIe port has ASPM
disabled, 2011-07-29) is supposed to have fixed a regression
introduced in v2.6.35, which is way later than v2.6.32 (and the patch
causing it does not seem to have been backported).  I guess it would
be useful to know what chipset you use.

Please attach output from

	/usr/share/bug/linux-image-$(uname -r)/script 3>&1

and "dmesg" output from right after booting.
