Bug Description
* The problem started with linux kernel 5.3.0-46
* When the screen (GPU?) is used intensively, I can hear coil noise from my laptop (Dell XPS 13)
and then the whole system will freeze during 5-6 seconds. During freeze I can move the mouse cursor, but nothing else is responding. During freeze, the noise stops. Then the systems comes back to normal for a few seconds (randomly from 10sec to 1 minute), and then the freeze repeats again and again.
* According to my experience, I would strongly bet that the coil noise is due to graphics.
* The hang is reported in the dmesg log:

* I have a small demo which uses the GPU intensively (via the SDL library) and I can repeat the freeze easily by running it.
* The problem does *not* occur with 5.3.0-45-generic (no noise, no freeze)
