Comment 11 for bug 1641976

There are a couple of things in kern.log.1 with 4.8.0-26, but if the dates in the log can be trusted they're from about a week ago. One of them looks like the same issue as in bug 1630774, and that one has a fix in 4.8.0-28.30. That build is still in the c-k-t ppa waiting to be copied out to -proposed, so could you give that build a try and see if it helps?

The other thing is a soft lockup which doesn't make any sense to me yet.
