Subject: [Regression, 2.6.36-rc1] ath9k resume problem on Acer Ferrari One

Hi,

While testing 2.6.36-rc1 (with a couple of fixes on top) I noticed that the ath9k
driver didn't work after resume from suspend to RAM.  An attempt to unload the
driver using rmmod caused the BUG_ON() in kernel/workqueue.c:2844 to trigger.

I wonder if that regression is a result of the recent workqueue changes?

Thanks,
Rafael
