Then go ahead and close with some nice status :) I didn't see any page fault spewing into my logfiles, but then again, the uptimes are sub-day on my workstation, and most of the time it spends suspended. What I did see is unusual degradation of the wifi download speed, while upload speed seems to be fine. But I cannot link it directly to enabling MMU or iommu kernel flag, just that Windows is having same problems, can be this cheapo TP-Link card, or my wifi signal, who knows... Anyways - thanks for your assistence with working around this problem...
