--- Comment #3 from Florian Evers (florian-evers@gmx.de) --- Hi,
new info: this "crash" can be reproduced very easily here on my system. It is enough to switch the screen off and on again to find the dump in the dmesg log. I did not test yet whether it happens during switching off or while switiching it back on, but I may test that using a second box.
I first noticed that the crash never happens if I work or play on my computer, but if I come back after a pause I certainly found it in the logs. Thus I got the assumption that it happens during the power saving phase of the screen. Interestingly, using the power switch of the screen the dump can be triggered very easily and 100% reliably.
Hope this helps!
Regards, Florian

--- Comment #4 from Tristen Hayfield (tristen.hayfield@gmail.com) --- I'm seeing this on the 5.10.* series as well. Currently 5.10.23, Gentoo. Radeon RX 5500 XT.
Looking at the offending section of code, it seems an assertion is being triggered:
// Fallback: Try to only support G6 temperature read latency context->bw_ctx.dml.soc.dram_clock_change_latency_us = context->bw_ctx.dml.soc.dummy_pstate_latency_us;
voltage_supported = dcn20_validate_bandwidth_internal(dc, context, false); dummy_pstate_supported = context->bw_ctx.bw.dcn.clk.p_state_change_support;
if (voltage_supported && dummy_pstate_supported) { context->bw_ctx.bw.dcn.clk.p_state_change_support = false; goto restore_dml_state; }
// ERROR: fallback is supposed to always work. ASSERT(false);
So one of (or both) voltage_supported and dummy_pstate_supported are evaluating to false here and falling through to the assertions.
Stack trace attached for completeness' sake. Hopefully a dev that understands the hardware will take a look at this one day and find it helpful.

I added the following line before the assertion and recompiled the kernel: DC_LOG_ERROR("voltage_supported: %d, dummy_pstate_supported: %d\n", voltage_supported, dummy_pstate_supported);
When the issue triggered again, it logged: [drm:dcn20_validate_bandwidth_fp [amdgpu]] *ERROR* voltage_supported: 1, dummy_pstate_supported: 0
So in my case the assertion is being triggered because dummy_pstate_supported is false and the fallback is not working as intended.

--- Comment #5 from Tristen Hayfield (tristen.hayfield@gmail.com) --- I did some more digging into this. 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.
