After about 10 emails with Asus support, I have managed to get their attention I think. They asked me to fill out an engineering test form to describe the problem and the solutions I have tried. I hope (perhaps naively) the detailed form I filled out is getting sent to engineers and not random IT/Support people. Fingers crossed. If they give me a beta BIOS that works I will immediately upload it here.

I have the exact same problem for the exact model of laptop (GA502 Asus Zephyrus with Ryzen 3750H). I managed to downgrade to BIOS 203 and the problem still shows up (but later in a stress or Gaming situation). The following BIOS versions all have the .39 GHz power state firmware bug: 203, 205, 206, 207, 208 These are the only ones I have access to. If anyone has 204 I would love to try it. Personally, I am 95% certain (arbitrary number I know) that this is a BIOS issue with AMD ASGEA. We need Asus to release a new BIOS that has ASGEA ABBA included. I am a test engineer for a large fab-less chip company. This kind of dumb problem seems like a firmware issue. It appears that when the CPU hits max temp, the firmware throttles directly to the lowest power sate.... and stays there until a hard reboot. Different BIOS's (in my tested list above) behave slightly differently (throttle down at 90 c vs 92 c) but the core (pun intended) issue is that the firmware throttles the chip down to .39 GHz and locks it there.
