My current hypothesis is that the via usb host controller resets under some unknown conditions. Michael Krufky has one report of a similar issue with the DViCO FusionHDTV Dual Digital 2 which uses the same USB host controller. I found a post in an australian mce forum which suggests that the via usb chip s troublesome (http://www.xpmediacentre.com.au/community/tv-tuners-digital-analogue/15203-dvico-dual-4-a.html#post109478). > Since the > DVB drivers don't handle hot-swapping, this causes a cascade of > errors through to the application (including a kernel oops).

I had not a single crash in the last two weeks. I use following patch to disable the eit scan for both the Nova-T 500 adapters: http://svn.mythtv.org/trac/ticket/2741 btw: disabling the scan on only one of the adapters didn't help.
