I filed this to hopefully avoid anyone else getting hit by it. I haven't hit it in months running 5.2, so in that sense it's rare. But upstream has maybe 1/2 dozen reports of it, and that's unusually high. https://bugzilla.redhat.com/show_bug.cgi?id=1751901 Is that enough information to carry that patch before it ends up in a stable version from upstream? I checked https://src.fedoraproject.org/rpms/kernel/pull-requests but it doesn't look like you really want PR's there. -- Chris Murphy
