Public bug reported:

I get a Kernel oops that affects the usb driver. After the oops, all usb
ports are dead and reboot seems not to work properly, too.

I cannot provoke the oops to happen, but it occurs about once or twice a
week, apparently after the computer goes to power saving mode and turns
off the screen. There is a usb hub built-in the monitor.

Dmesg output is attached, ubuntu-bug linux outputs are below.

Other reports I found that look similar:

There are patches for similar-looking bugs:
(however, I do not understand these posts really)
