Weird.  I can't find any obvious candidate for a patch that would have
broken the driver.

Can you bisect?  Even a few iterations would help a lot in narrowing
down the search.  It works like so:

	cd linux
	git bisect start
	git checkout v3.2.21; # vanilla kernel
	make deb-pkg; # optionally with -j<num> for parallel build
	dpkg -i ../<name of package>; # as root
	reboot
	... test test test ...

	# hopefully it avoids the bug, so
	cd linux
	git bisect good
	git checkout debian/wheezy; # patched kernel
	make deb-pkg; # maybe with -j4
	dpkg -i ../<name of package>; # as root
	reboot
	... test test test ...

	# hopefully it reproduces the bug, so
	cd linux
	git bisect bad

	# a rev halfway between is automatically checked out
	# to test
	make deb-pkg; # maybe with -j4
	dpkg -i ../<package>; # as root
	reboot
	... test test test ...

	cd linux
	git bisect bad; # if it reproduces the bug
	git bisect good; # if it reliably does not
	git bisect skip; # if some other bug makes it hard to test

	# another rev to test is automatically checked out

	... continue until it finds the "first bad rev" ...

At any step you can watch the regression range narrowing by
running "git bisect visualize" if the gitk package is installed.
When finished or bored, please run "git bisect log" to list revs
it has tested so others can analyze your results or pick up where
you left off.

Thanks again, and sorry I have no better ideas.

Sincerely,
Jonathan
