okay, i've update the firmware on my older Raspberry Pi 4 to the same 
version as yours. But even with your configuration i don't see this kind 
of fallout. So I think we shouldn't apply this patch until we really 
know what's going on.

You don't have another Raspberry Pi 4 by any chance?
Another cause might be the toolchain. Currently I use a not so fresh gcc 
11.3.1 from Linaro.

Except of this, I noticed that your configuration doesn't enable 
DWC2_DUAL_ROLE and the LEDS_TRIGGER.

Best regards
