Subject3.3.0: Oops when resuming from hibernation
Date
Hi,


I'm getting oops, when my laptop is resuming from hibernation (hibernated by KDE). If I hibernate again without reboot, it won't wake up anymore. My bluetooth mouse (Logitech V470) works before hibernation, but not after. I have to reboot
to make bluetooth work again.
I can reproduce this oops with every hibernation. This is regression in linux 3.3.0: bluetooth has worked correctly before (since 2.6 days to 3.2.14). The problem still exists with 3.3.1 (which introduces another problem with ath9k not
connecting to AP, which is why I'm stuck with 3.3.0)

I'm not sure if this bug is in usb, bluetooth or hibernation, so I send this mail to lkml.
