[mythtv-users] Hauppauge HD-PVR trials and tribulations.

[georgia_tech_swagger]

I disabled XHCI entirely in the kernel and BIOS, rebooted into the new
kernel, same result.

3.17.6 does seem to be better (~20m average until lockup) than the 3.16.5
kernel (~5m) ... but still unusuable.  I'm trying 3.18.1 now.
