hello > Sorry, I was on holidays and only playing catchup now. Does this happen > to trigger with 5.2-rc3?

I have built v5.2-rc3 from git (stable/linux-stable.git) and tested it against firefox-67.0.1 build: no joy. I'm going to upload the kernel log and the config I used for v5.2-rc3 (there were a couple of new opts) to bugzilla, if that can help thanks ciao -g
