Raimonds and Jurgen,
Can you both test with the following patch applied to the driver:
Raimond, do you still see the AMD iommu faults with this patch?
I have limited access to this box at workdays. I will try to test
your patch tomorrow.
Unfortunately I still see AMD iommu faults.
Test environment:
kernel: 3.18.1 (I was unable to compile drivers on kernel 3.13.10)
media tree: pure main media tree + your patch
test: 1) warm reboot
2) run command "w_scan -fs -s S13E0 -D0c -a X"
where X - receiver's number
Tests were run on single receiver
Observations:
1) Tests were run three times on first receiver and three times on second.
Only one test from three failed on first receiver.
All tests failed on second receiver.
2) I have feeling that with your patch faults on first receiver appear
less often
but this may be pure luck or placebo.
