JFYI: I added this report to the list of regressions for Linux 4.9. I'll watch this thread for further updates on this issue to document progress in my weekly reports. Please let me know via regressi...@leemhuis.info in case the discussion moves to a different place (bugzilla or another mail thread for example). Current status (afaics): Patch available tia! Ciao, Thorsten P.S.: Thx for CCing me!
