You are right, it does NOT happen. I managed to get somehow a piece of the stacktrace before the usbserial
on the affected host died:

Also, there is a message

[ 525.302615] sysfs group ffffffff8194f980 not found for kobject '0000:11:00.0'

when I was rebooting the computer. I think this might be pointing to the place of crash as well.

Once again, does not happen with 3.2.14 but does with 3.3.4 as well.

I will learn to use the echo trick always for this USB3.0 express card and and we came to that
already, it only happens when xhci_hcd was loaded and claimed the device.

In the attached traces are actually two bootups. In the former I got the Ooops.
In the second I used carefully the echo command to "unplug" the card from xhci_hcd
before physically removing it. But at the very end I few times omitted teh echo trick.
So at some point you will see different messages logged. And that is why at the very
end when system was to reboot, sysfs complained.

Thanks,
Martin
