[Solved] Video every other boot

Hi all! Not exactly new, but having a massive brain cramp. I've got long-covid and it leaves me awfully confused a lot, so if someone would be so kind as to point me in a direction for troubleshooting, I'd be eternally grateful.

This is a relatively new, all AMD system:
Graphics: 6750 XT
CPU: Ryzen 5 7600

The trouble is, I only get video sometimes when I boot, and I'm unsure of why. From cold the system will come up all the way to Grub, but then as soon as Grub finishes and the kernel takes over I just get a black screen and the system becomes totally unresponsive (ctrl-alt-del) doesn't even work - I have press the reset button. ssh doesn't even start, and I can't seem to find anything in the logs, though that may simply be because I haven't had to do this in a while and my brain is not so good anymore.

Thanks all!

Re: [Solved] Video every other boot

On a random guess, though that should be default by now lack of early KMS: https://wiki.archlinux.org/title/Kernel … _KMS_start -- on a guess because it's stupid: disable the simpledrm device by adding "initcall_blacklist=simpledrm_platform_driver_init" to your kernel parameters.

If neither of these help, from a working boot post the link resulting from

sudo journalctl -b-1 | curl -F 'file=@-' 0x0.st

Re: [Solved] Video every other boot

You say every other boot. Are you restarting your PC or shutting down?

Some people have reported reboot issues on some AMD GPUs, were a reboot doesn't work properly, but a shutdown does.

This is from cold - reboot always works flawlessly, oddly enough. I'm about to post a more general update as well. Thank you!

Thank you so much for your recommendation. Oddly, your first suggestion seems to have corrected the issue totally. Thank you again, and my apologies for such a delay in responding: Validating intermittent fixes is always a hassle.
