@jsalisbury: I had the machine tested with this kernel:
Linux xa-xubu 4.18.0-041800rc1-generic #201806162031 SMP Sun Jun 17
00:34:22 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
that I found via your link [0].
The result is that in this kernel, the problem is gone. So that sounds
like good news!

Yes, the problem started after an upgrade. From what I can see in the logs it
seems that first the machine was upgraded from Ubuntu 17.10 to 18.04,
apparently without problem.
Then a few days later, the working kernel Ubuntu 4.13.0-43.48-generic 4.13.16
was replaced by 4.15.0-23.25-generic
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.17
Oops, the above message was not supposed to be mailed here...
