I have a Lenovo X220 with:
03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35)
Subsystem: Intel Corporation Centrino Ultimate-N 6300 3x3 AGN
Flags: bus master, fast devsel, latency 0, IRQ 50
Memory at d2500000 (64-bit, non-prefetchable) [size=8K]
Capabilities: <access denied>
Kernel driver in use: iwlagn
Kernel modules: iwlagn
With 3.0-rc1, I'm seeing these in dmesg:
DRHD: handling fault status reg 2
DMAR:[DMA Write] Request device [03:00.0] fault addr ffe8a000
DMAR:[fault reason 05] PTE Write access is not set
DRHD: handling fault status reg 2
DMAR:[DMA Write] Request device [03:00.0] fault addr ffd5a000
DMAR:[fault reason 05] PTE Write access is not set
DRHD: handling fault status reg 2
DMAR:[DMA Write] Request device [03:00.0] fault addr ffd52000
DMAR:[fault reason 05] PTE Write access is not set
but the device seems to be working OK.
Thanks,
J
