dmesg log

When using discrete radeon gpu on my laptop in most application(via PRIME) I
constantly get gpu hung.

I can reproduce this bug in glmark2. bug ALWAYS happens on [desktop] stage of
benchmark. also this is not hardware problem(gpu works fine in windows/ no
overheating)
Please help me, I cant use discrete card for a year now because this bug.

There is call trace in dmesg somehere in the middle(full logs attached):
