Hi Milan
[+linux-rockchip to see if someone has a Samsung chromebook one plus
and could confirm if it works]

Hello,
Sorry to annoy again, but could you tell me if I sent this bug report
to right mail address or I should send it somewhere else.
Also, did I sent bug report correctly or I did some mistakes which
caused it to be ignored.

Hello,
I'm not native English speaker and I'm self taught in English so sorry
if do not write or express correctly. And sorry if I posted bug report
to wrong address.
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 5.2.1 and up) but I'm getting error messages in kernel
after machine resumes from suspend-to-ram.
It sounds to me suspend-to-ram never works for this machine, at least
since 5.2.1. Am I right?

I invoke suspend-to-ram by `echo mem > /sys/power/state` from ACPI power
and LID button handlers.
This only happens when I boot and use internal emmc card and never when
boot and use external mmc card.
If suspend-to-ram is not invoked (machine is always in normal state)
this problem never happen (or I missed it somehow).
I'm attaching kernel .config (file config-5.6.0-rc3-1-gru.conf) which
use to build kernel, output of the `awk -f scripts/ver_linux` as file
ver_linux.txt and output of dmesg as file mmc-err.txt (from which I
deleted wifi connection logs).
Sorry if I did something bad or wrong with this bug report, I don't have
much experience with bug reporting, especially for kernel.
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
