Bug Description
When I suspend the screen turns black and the mouse cursor remains frozen on the black screen. There is no reaction to any key or power-button press even Alt-Sysreq-B stays quiet. Only a hard power-up reset helps (yes, indeed with the front button pressed a longer time).
My previous kernel was ubuntu 5.0.0-29-generic. With this kernel I had no trouble with suspend. Since kernel ubuntu 5.0.0-31-generic or 5.0.0.32-generic suspend fails. I tried without luck the kernel 5.3.0-19-generic.
Its a desktop computer from Lenovo V530-15ARR
