I put some logging inside the if block to see if that branch is ever taken: if (voltage_supported && dummy_pstate_supported) { context->bw_ctx.bw.dcn.clk.p_state_change_support = false; goto restore_dml_state; } in order to log when or if the fallback worked. The logs confirmed that the fallback is often used and generally works. Upon starting up the system and starting up Xorg I get about a dozen log messages indicating that it entered the if block. The only exception seems to be as Florian describes above, that when the display shuts off due to power-saving it triggers the assertion. -- You may reply to this email to add a comment.
