In the past with my tuners based on these chips, I had to really power
off the server. I would shutdown the OS, remove power from the PSU,
try to turn on the PC (the fans would turn momentarily), scratch my
head for 30seconds, just to be sure there is no power in the system,
replace power lead and boot up.
This forces the tuner chip to boot from 'cold, which will include a
reload of the firmware. If it is doing a 'warm' boot, it already has
the firmware and doesn't reload it.
You should see messages in dmesg which relate to 'dvb' or 'DVB' and
indicate whether it is a warm or cold boot.
