--- Comment #16 from Andrey Grodzovsky (andrey.grodzovsky@amd.com) --- What kernel version are you using ?
We can try and figure out what was the last commands in HW before you experienced the page fault.
You can clone and install our register analyzer from here - https://cgit.freedesktop.org/amd/umr/
Then launch your X with ENV variable GALLIUM_DDEBUG=always to dump all the 3D commands into files in ~/ddebug_dumps/
Run your workload.
After you again experience the GPU page fault please provide the following outputs
sudo umr -lb sudo umr -O verbose,follow_ib -R gfx[.] sudo umr -O bits -wa sudo umr -O many,bits -r*.*.mmGRBM_STATUS sudo umr -O many,bits -r *.*.HEADER_DUMP sudo umr -O many,bits -r *.*.CP_EOP
