I have also a reproducible "hysteresis"-effect with regards to my RX460 GPU: When I experience the bug scenario I reported in <a class="bz_bug_link bz_status_NEW " title="NEW - System crashes after "[drm] IP block:gmc_v8_0 is hung!" / [drm] IP block:sdma_v3_0 is hung!" href="show_bug.cgi?id=102322">https://bugs.freedesktop.org/show_bug.cgi?id=102322</a> 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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
