It was happening daily previously when running the Ubuntu 2.6.20-4-generic kernel which was based on the rc2 or rc3 kernel (not exactly sure). The behaviour leading up to the oops was a little different this time. It started with the usually disconnect and reinitialize.... this happened at the start of a mythtv recording. usb 3-1: USB disconnect, address 2 The oops didn't occur until mythtv completed the recording 30 minutes later. Myth must have thought the recording was working, but nothing was saved to file. BUG: unable to handle kernel paging request at virtual address 008c4530 Do any of the developer have any idea what could be causing these? I'm happy to enable whatever debugging is required to help track this down. I've seen some comments (from Michael Krufky and others) that the reason for these types of oops' is that DVB core is not hot pluggable. This card is a PCI card that contains a USB hub, so in theory will never be disconnected. But when these disconnections occur (for whatever reason), the DVB core cannot handle this and causes the oops. Are there any plans to make the dvb core support hot plugging? This could help both the USB stick devices that are intended to be plugged in and removed from a running system ... but I assume it would also help when an internal USB card has a mysterious disconnection. I'm wondering what path would be best to try to resolve the Nova 500 crashes??
