I also have this problem. It seems to vary (a lot) with kernel versions
and in my case does not appear to be temperature-related. I believe it
is to do with some sort of USB bus lockup, because when it occurs I also
have issues with other USB devices.

What fixes it for me is not only a reboot of the server: a power cycle
of the tuners is also required. So I got myself a software-controllable
switching power socket so that I can switch power to the tuners off
before rebooting and on again afterwards.

But this problem has now become very rare for me. I can't remember when
I last had to reboot due to this issue but it's many months ago.
