--- Comment #9 from David Breese dabreese00@gmail.com --- This did not fix the issue. Still present in kernel 4.4 and 4.4.1, both of which I believe contain the relevant commit mentioned in bug 91268.
No idea what this means or if it will be any use, but I notice that running without "iommu=soft" on the kernel command line, suddenly the bug starts occurring more than once an hour. I have been running with "iommu=soft", in which case the bug seems to happen more like once every 20 hours of X11 use.
Otherwise, mostly still the same package versions and dmesg as posted above, but I can post the precise new info if desired. Let me know what info I can provide that would be useful.
