Ultimate SSAO in Tomb Raider causes GPU reset event [RX 5700 XT]

Setting SSAO to 'Ultimate' in Tomb Raider causes a reset event:

Apr 05 16:08:15 enterprise kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx_0.0.0 timeout, signaled seq=147661, emitted seq=147663

Apr 05 16:08:22 enterprise kernel: amdgpu: [powerplay] SMU is resumed successfully!

This is entirely reproducible: change preset to 'Ultimate', reset occurs; change preset to 'Ultimate' and drop SSAO to normal, reset does not occur. Reset does succeed most of the time, though DisplayPort audio stops working until the next reboot.
