Before 5.4 was available, I came across reports linking this to a USB controller of all things, like https://www.mail-archive.com/debian-kernel@lists.debian.org/msg116563.html. In my case the cuprit was: 06:00.4 USB controller: Advanced Micro Devices, Inc. [AMD] Raven USB 3.1 so I started removing the device from the PCI tree before suspend using /sys/bus/pci/devices/0000:06:00.4/remove and rescanning the PCI bus on resume. First manually and later though a systemd hook. That worked around the problem until 5.4 "fixed" this. -- 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
