Title:
  irq 16: nobody cared usb_hcd_irq

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I am using a PCI card which is the Nova-T-500, a double tuner DVB-T card with "Description:	Ubuntu 12.04.1 LTS
  Release:	12.04 (Ubuntu 3.2.0-35.55-generic 3.2.34)". I get random IRQ bugs with it which make my DVB card not usable. I have tried everything on this webpage: . I have disabled what I could in the BIOS, I have updated the BIOS, I have tried tried all the kernel parameters, I have tried to put the card on another slot (sometimes the computer didn't boot on the other slot, sometimes I still had the bug) without any success...

  Here is the interrupts list:

  On the forum I have been told that a kernel panic was related to a irq problem: http://ubuntuforums.org/showthread.php?t=2098028
  Basically when I try to convert a file with ffmpeg, I get a kernel panic, maybe it is related to that irq problem.
