Public bug reported:
Hello there!
I have an HP 840 G5, with an external docking station (HP USB-C Dock G4). All
the input and output devices are connected to this docking station"
- display on Displayport (x2)
- ethernet
- keyboard
- mouse
After I turn on the machine in the morning (probably from S3 sleep), it just
blinks the displays for a few moments, than it turns to black for seconds and
this is an endless loop. If I reconnect the docking station I can get back one
of the displays to life, but the other one remain in sleep state.
In the meanwhile after each of these problems, the intel_pstate driver seems to
fail, all the processors cores are clocked to 3.6GHz.
If I reboot the machine, both the screens are usable again and the intel_pstate
driver is able to change the freqency.
Kernel version 5.0.0-23 was not able to lower the frequency at all, I had to
use the ondemand scheduler.
I found these lines for about 5 days in a previous dmesg log.
