Can you test 4.2.6 with iommu = soft as a kernel parameter, please?

Comment 3 DJ Dunn 2015-11-19 15:27:53 UTC

I will try to get to that tonight

Comment 4 DJ Dunn 2015-11-21 03:18:29 UTC

seems to have gone away with 4.2.6, though i didn't sit and watch it for long before throwing on 4.3.0 vanilla, haven't seen it there either
