This evening, I've received a complaint about the noise of the fan,
which can be heard throughout the house.
PLEASE can we sort something out about this damned fan? I know that
there's a PWM control of it, so let's get it more under control. If
no one is interested in writing a driver for it, then please supply
me with the information so that I can sort this out, and stop it
being so annoying.
Like I've said above, right now the board doesn't stay on for very
long, and it's actually a very big _demotivator_ to powering the
board on.
This board is also *never* going anywhere near my boot farm because
it's just too damned noisy to be powered up during the night, even
if we do get the fan more under control once the kernel is running.
If that's not enough to get some help with this, I'll instead snip
the fan wire and solder a resistor in series with the fan to slow
the damned thing down to reduce the noise level.
