Moi Malcolm,
Any idea why this seems to crash Kernel just when device is plugged?
Hi Antti
Yes, there missing error handling when no firmware file found.
It seems that this is more of a problem with udev-182+.
However, so far udev-182 is only a problem on first ever plug.

It is good to print needed fw name. I found it from the documentation,
Documentation/dvb/lmedm04.txt.
Could you drop me that firmware privately as I don't wish to install
Windows drivers in order to extract it.
