It was reported here: https://bugzilla.kernel.org/show_bug.cgi?id=3D219205 Also it was recently reported in the Debian tracker after checking if the latest Debian stable is still affected: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D1117959 Unfortunately, the Debian team cannot act on the report because no one from the upstream kernel team has confirmed if the report in the upstream tracker is valid or not. Therefore, I am checking if anyone can help confirm if the observed behavior is indeed a bug. Many thanks in advance! Regards, Garri
