RX560: Lock-up after resuming from hibernation
When I hibernate and resume, everything seems fine: The machine reboots and seemingly returns to the pre-resume state. It also shows the login prompt of the KDE screen locker. However, if I either switch from the KDE screen to a virtual “text” console or if I enter my password, the display and console lock up (I cannot even login blindly) although login via SSH works and the machine can rebooted normally.
This happens no matter if I hibernate directly from KDE or switch to the console first (in the latter case the machine shows the login prompt of the console but once I switch to the KDE console, the screen locks up once I have entered my password or tried to go back to the console).
This bug is ages old and goes back to some 4.x kernel version.dmesg-hibernate.bugzilla
