We have a large university system in the UK that is experiencing
very long delays modprobing the driver for a specific I/O device.
The delay is from 8-10 minutes per device and there are 31 devices
in the system.  This 4 to 5 hour delay in starting up those I/O
devices is very much a burden on the customer.
That's nuts.
Agreed, and I'd suggest marking this for -stable, once it's all 
settled and tested.

Thanks,
