Comme= nt # 31 on bug 10573= 3 from Jan Jurzitza 
I have found a workaround (amd patched kernel not required):

cat /sys/class/drm/card0/device/pp_dpm_sclk
# insert appropriate index here, I went for 1077Mhz
echo 3 > /sys/class/drm/card0/device/pp_dpm_sclk

Makes the GPU a bit slower (changes clock to 1077 Mhz on my card) for the
session, but at least applications don't freeze the system anymore now (or =
at
least this is delaying it so much that it works for multiple hours, but it
didn't freeze for me yet)

Though because of the slowdown I don't think this is a good solution long-t=
erm.
Maybe a hint towards a solution though maybe? What I noticed in radeon-prof=
ile
is that on auto it is capable of running at the boost frequency (1266 Mhz) =
and
not limited to the base frequency the product page specifies (1120 Mhz) by
default, so I changed it here and it basically fixed it.

Fixes the issue on kernel 4.18.4
