I have very strange problem which I don't know how to debug and solve.
My laptop DELL 5490 freezes from time to time during display off (after session locking), going to sleep mode or hibernating (after lid closing).
Under term "freeze" I mean CPU heating with maximum fan speed and no reaction to any key or short power button press. The laptop may be turned off only by long press to power button.
OS: Installed RHEL from 8.0 after upgraded to 8.3, encrypted LVM,
Display Manager: Gnome on Wayland. On Xorg the same issue.
Please help to identify the problem and solve it!
