I haven't had a chance to bisect the issue. I'm busy fighting all sorts of fires related to kernel 5, which in general has been a disaster. Almost every new version breaks more stuff (5.1 broke the chromebooks, 5.2 broke some of our servers, 5.3 broke the e1000e driver, the list goes on).
So I'm still stuck running older version 4 kernels for a while.
Still broken in kernel 5.3.1.
