Hi,

I got the following when I powered off my laptop. Normally it powers off
without problems but this time it didn't and I managed to write this down
by hand. I didn't write down the stack frame information. Don't know if
this is useful.

Debug: sleeping function called from illegal context at include/asm/semaphore.h:119

Call Trace:
     driverfs_remove_file
     device_remove_file
     pci_pool_destroy
     hcd_buffer_destroy
     usb_hcd_pci_remove
     pci_match_device
     device_shutdown
     unregister_reboot_notifier
     force_sig_info
     kill_proc_info
     notify_parent
     dput

Power down.
