--- Comment #59 from dwagner <jb5sgc1n.nya@20mm.eu> ---
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=102322 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 HDMI
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 the 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.
