Newly captured GCVM_L2_PROTECTION_FAULT errors. This was captured on 5.4(rc)
kernel, and with AMD_DEBUG=nodma.

I got a few more freezes when using Nemo. This time with AMD_DEBUG=nodma or
AMD_DEBUG="nodma,nongg".

I put AMD_DEBUG to /etc/environment, and I can indeed confirm it from terminal
(echo $AMD_DEBUG). It seems this doesn't work, as the freezes I got this time
are also sdma0 type, same as before.

I also captured some new GCVM_L2_PROTECTION_FAULT errors. Not sure if they're
different from last time. This is captured on 5.4(rc) kernel with
AMD_DEBUG=nodma.

In the end, the sdma0 error doesn't seem to go away and I'm not even sure
whether the parameter was set correctly. Where am I supposed to put the
AMD_DEBUG parameters on Manjaro?
