DVB-T dib0700 one minute hang when resuming

[Gonsolo]

Hi!

The following script fixes an annoying 62 second hang when resuming 
while my Nova-T stick is connected to my notebook.

echo /etc/pm/sleep.d/50_dvb_usb_dib0700_quirk:

#!/bin/sh

case "$1" in
  hibernate|suspend)
   rmmod dvb_usb_dib0700
   ;;
  thaw|resume)
   modprobe dvb_usb_dib0700
   ;;
  *) exit $NA
   ;;
esac

Is the right fix to use request_firmware_nowait?

Thank you.

Do you have any idea why it doesn't find its firmware?

Known issue. I have no idea where to start look from.

Don't know. Maybe it's because it is not included in initrd or user 
space is still not available when resuming. In the first case it is a 
Ubuntu Kernel bug, in the second case the driver has to be fixed by 
using request_firmware_nowait. But please notice that I am absolutely 
not qualified to answer this question. I was hoping to get an answer on 
that issue since this is the last annoying bug that keeps my 
Ubuntu/Debian/Gnome/GNU/Linux distribution from being perfect. :)
