And the problem was...
udevd was dead, so it couldn't load the firmware. It took me a good
guessing effort for realizing that firmware is loaded by udev, I was
indeed experiencing the same loading firmware problem with another
module and finally I read something about the firmware being loaded by
udev.
Please improve the behaviour of the module so that it will check for
the presence of udevd and tell explicitely if it isn't present rather
than hang forever trying to load the firmware.
Anyway, bug report has to be considered closed, now I have to
understand why udevd was dying...
Thanks, regards.
