I can confirm that the problem stopped when I removed my NIC. Now IRQ 16 is only used by my video card.

Status in “compiz” package in Ubuntu: Confirmed Bug description: Like a number of other users, I'm getting some variant of graphical slowdown after using my desktop PC for a random amount of time - between minutes and hours. I suspect the problem lies with compiz, OpenGL or graphics card drivers (NVidia in my case) as I have seen this behaviour with both Linux Mint 11 and 12 in the past, on the same PC. I don't believe there to be a hardware problem as this machine works perfectly fine running high-end games under Windows. Restarting or logging out and in often temporarily resolves the issue... but it eventually returns.
