Hi Alex,
I've attached what you've requested after I reenabled iommu.

Hi,
I have an AR9462 connected over minipcie, it came with the ASRock
FM2A88x-itx motherboard and I'm using an AMD A10-7850K cpu with it. When I
have IOMMU enabled, and this is desirable for opencl related things, the
AR9462 malfunctions with these two errors occurring:
AMD-Vi: Event logged [INVALID_DEVICE_REQUEST device=00:00.1
address=0x00fdf8080020 flags=0x0a00]
Followed by this looping error, which reoccurs shortly after associating
and obtaining an IP. I've attached a large snippet from dmesg, due to it's
length.
I'm not sure where the error is coming from but I did see that Alex
Williamson posted a patch that dealt with aliased devices (like pci
bridges) and AMD's IOMMU issues, see
e028a9e6b8a637af09ac4114083280df4a7045f1 for reference.
I then disable IOMMU in the bios, and immediately the ath9k/AR9462 pair is
working without flaw or retries. Bios is up to date btw, updated it after
building the machine last friday.
So anyone have a clue what's going on here?
Please boot with amd_iommu_dump on the kernel boot line and send the
full dmesg log and 'sudo lspci -vvv' output. Thanks,
Alex
