Virtually all of the March deployments involve some sort of bug that causes my system to hard freeze, sometimes within 15 minutes of being left idle, nearly always after being left on over night. The screen will be frozen with the time on it so I can see when it happened, but there are no logs whats…

Nope, it’s completely toast. No tty switching, sysrq, SSH, etc.

I am having the same issue, also on AMD, did you find a fix?

EDIT: I found a (horrible) work around… a mouse jiggler keeps it from doing whatever it does when left idle, and it doesn’t lock up. (sorry for the re-post, hit the wrong reply button and nested this under someone else’s post) I’m having the exact same issue; hard freeze, system does not respond …

It appears to be a known issue with the amdgpu driver. Moving back to kernel 6.14 is a slightly better workaround than a mouse jiggler. kernel-6.14.0-63.fc42 - Fedora Packages is the original kernel, still available on their servers. Reverting to this kernel has stopped the lockups for me. Hopefull…

And indeed, kernel-6.16.2-200.fc42.x86_64 has been released, and after about 9 hours of idle time it locked up solid. 6.14 lasted about 4 days before 6.16 was released. 6.14 it is then.

Unfortunately I have not found a fix, other than to be more aggressive about putting the computer to sleep when I’m not using it. That’s avoided a hard freeze for the last couple of months at least. It’s too bad because these bugs were the reason I switched to Kinoite when they were rendering my co…

It’s been a couple of days now and the 6.16.4-200 has been perfectly stable for me. I think they’ve fixed the problem.

Glad to hear it, I was about to post that I had to keep my computer on for ~2 days on 6.15.10-200.fc42.x86_64 with no crashes. I will say that the issue has seemed to come and go over the last year or so so keep an eye out for it I guess :slight_smile:

Well, after weeks (or months) of no issues I had a hard freeze with exactly the same symptoms yesterday. I’m guessing it’s been partially mitigated to the point where it happens far less frequently but maybe there are still some edge cases?

And I got another freeze today, this time after only idling for a few minutes. Hopefully there hasnt been a regression but at this point I’m almost about to buy an Nvidia card because this show-stopping bug has been really persistent over the last ~8 months and it’s just frankly getting a little rid…

I also had another freeze this week, and since my last comment, probably 10.
