Hello,

This is one of first bug report to linux kernel, so sorry if I do
something wrong or inappropriate. And I'm self taught in English so
sorry if do not write or express correctly.

I'm running linux 5.6.0-rc3 without any patches on Samsung chromebook
one plus, Arm64 rockchip rk3399 based model name:
Machine model: Google Kevin

I build kernels from upstream git.kernel.org for this machine for some
time (iirc, from 5.4.1 and up) but I'm getting error messages in kernel
about 'psr' related to analogix driver, which I see with `dmesg`.

This bug appears in `dmesg` output few times on a days but randomly and
I can't find any correlation of the work with machine and appearance of
this bug.

I have no experience with with video drivers so don't know how to debug
this problem more deeply.

I'm attaching kernel .config (file config-5.6.0-rc3-1-gru.conf) which I
use to build kernel, output of the `awk -f scripts/ver_linux` as file
ver_linux.txt and  output of dmesg as file dmesg-br3.txt (from which I
deleted only wifi association log).

Sorry again if I did something bad or wrong with this bug report.

I'm ready to send you more data, and investigate this more, apply
patches and rebuild kernel or whatever you ask me (of course if my
understanding and knowledge is enough for this job).

Thank in advance
