Comment 26 for bug 1810546

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 -

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
