Exclamation [BUG REPORT] 260.19.36 64-bit Linux driver conflicts with AMD 890FX IOMMU

I'm running Kubuntu 10.10 Maverick with kernel version "2.6.35-26-generic #46-Ubuntu SMP Sun Jan 30 06:59:07 UTC 2011 x86_64 GNU/Linux". I'm using an ASUS Crosshair IV Extreme motherboard with 2 EVGA GTX 580s and when I enable the IOMMU in the BIOS I get this error in Xorg.0.log :

Code:

Checking dmesg reveals the problem :

Code:
[ 14.886270] AMD-Vi: Event logged [IO_PAGE_FAULT device=01:00.0 domain=0x0018 address=0x0000000214cc6200 flags=0x0010]

[ 22.895148] NVRM: rm_init_adapter(0) failed

Disabling the IOMMU solves the problem completely.

Hopefully Nvidia will address this soon.
