The machine is responsive, commands can be typed on the keyboard, SSH'ing is also possible. Somewhat unexpectedly, resume from hibernation works fine (i.e. there is signal). This started happening a few weeks ago, seemingly when `linux` v5.5.2 was installed. Was also present on v5.5.3 and v5.5.4 (current). `linux-lts` v5.4.20 does not exhibit this behaviour; it's a regression. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
