I don't think your observations indicate a hardware defect.

I have also a reproducible "hysteresis"-effect with regards to my=
 RX460 GPU:
When I experience the bug scenario I reported in
https://bugs.freedesktop.org/show_bug.=
cgi?id=3D102322 and then reboot by pressing
the reset-button, the BIOS greeting and the GRUB loader are consistently not
shown (just a black screen, but with the connected TV indicating a valid HD=
MI
signal), only once Linux sets the console video mode during boot, then the
screen lights up again. If at that point, or at any time thereafter I reboot
either by typing "reboot" or by pressing the RESET button, then t=
he BIOS
greeting and GRUB menu are shown as normal.

I think this is just due to some lack of thorough initialization upon reset,
because if I power down the machine by switching off the power supply, and =
then
reboot, the BIOS and GRUB menu always come up. Seems to me that pressing the
RESET button just isn't resetting as much as an actual power down does.
