Hi,
I have this device:
03:02.0 Network controller: Qualcomm Atheros AR9227 Wireless Network Adapter
(rev 01)
Subsystem: Qualcomm Atheros Device 0300
Flags: bus master, 66MHz, medium devsel, latency 168, IRQ 19
Memory at f7c00000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [40] #80 [0000]
Kernel driver in use: ath9k
which works great, except dmesg keeps being spammed with messages like
this one:
[ 2880.027256] dmar: DRHD: handling fault status reg 3
[ 2880.027260] dmar: DMAR:[DMA Read] Request device [03:00.0] fault addr
ffffd000 DMAR:[fault reason 06] PTE Read access is not set
Is this a driver issue or a hardware one? Can I somehow silence it
without disabling the use of the IOMMU?
Thanks,
