Nvidia lockup in Arch

Hey all,

Having some issues with the proprietary nvidia drivers. I'm getting lockups at random times. They start with a journal message stating:

NVRM: Xid (PCI:0000:01:00): 64, 155c(3fcc)  00000000 00000000

then giving the following a few times over:

NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context

A quick search of the google machine tells me that it appears to be a hardware issue. I was wondering if anyone had any experience with this issue. GPU is a 660 ti.
