Upgrading to the new nvidia drivers didn't really solve anything. 

My problem is mostly when moving around the menus and when more disc
activity is happening.

Looking at:


Im wondering if its an interrupt issue. 

I have a pair of SATA drives in the box - using hdparm -u1 /dev/sdX
results in the following error msg:

HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device

Anoyone know how to unmask (or get the status of) an interrupt for a
SATA drive?
