In this case it was on topic. The link explains how to use fancontrol script
from lm_sensors to work around fan control issues. I saw on another ticket when
I first posted here that dc=1 fixed the fancontrol issues. Finally I got dc=1
working and still it doesn't resolve the dpm fancontrol issues on my platform.

https://github.com/kobalicek/amdtweak
as root
# ./amdtweak  --card 0 --verbose --extract-bios /tmp/amdbios.bin
fails. The sysfs shows that the powerplay tables are not proper too.

[ 4969.713277] resource sanity check: requesting [mem 0x000c0000-0x000dffff],
which spans more than PCI Bus 0000:00 [mem 0x000c0000-0x000c3fff window]
[ 4969.713283] caller pci_map_rom+0x66/0xf0 mapping multiple BARs
[ 4969.713289] amdgpu 0000:01:00.0: Invalid PCI ROM header signature: expecting
0xaa55, got 0xffff

If it can't read it's powerplay table because it can't read the bios maybe
that's why there is all these problems.

Also the users above on this ticket above here when they grepped their dmesg
wouldn't have output any powerplay mes.sages because they grepped radeon
instead of amdgpu

[   10.124232] amdgpu: [powerplay] 
                failed to send message 309 ret is 254 
[   10.124248] amdgpu: [powerplay] 
                failed to send pre message 14e ret is 254 

Maybe Denis could confirm or deny if this is in his dmesg?
