[linux-dvb] Another Nova-T 500 Dual DVB-T Oops

Hi,

On my myth box I have a simple script that checks messages every 10sec and
reboots if the usb disconnect line appears, I collect timestamped copies of
the messages files.
A distinct pattern i still to occur, but some channels are worse than
others, but that might be time of day caused reception variations.

Starting recording 3min ahead gives the box time to reboot and resume
recording.
