Re: System randomly rebooting

Cheers Gnat. Ye I don't use arch much for past decade ; I forgot about the archive so indeed there are some downgradable versions. That's good.
I checked out the version I wanted from the ABS and built it. took 24mins whilst I was out somewhere and ye so far so good. Although from that first reboot I have ever seen like that, there was about 2 days almost from the recent kenrel update.. so I do not yet know if it's a kernel issue (or if it's ryzen only seeing this, a kernel induced hw bug). Either way, fingers crossed and gl.

Re: System randomly rebooting

After installing 6.10.4 and seeing the problem get slightly worse, I downgraded as suggested in post #49, to 6.10.2 and my system is behaving normally again.  No random reboots in the last several hours.

Re: System randomly rebooting

Great, so instead of a hanging GPU (seeminly not causing much issues) many amd users with integrated gpu (even if not using the igpu at all) now have cpu crashing issues?
This workaround seems to do more harm than good...

Re: System randomly rebooting

So i am following this thread since a couple of days (when i started to noticing reboot problems) i did not have yet downgraded to the correct 6.10.2, i was hoping that 6.10.4 could've solved the issue but it seems it is not the case. I believe i did not understand what the issue is completely, so the problem seems to be how manufacturers handle power management for amd cpus/gpus? And the problem of system reboots or gpu hanging is just a consequence of that particular kernel on those "bad power supplied" cpu/gpus ?
I'd like to learn more about the topic, just out of curiosity.

Also, i have amd microcode installed on my system i don't know if i can do anything more to mitigate the problem.

Kernel 6.10.4 and mesa 24.1.5-2 still crashes?

Re: System randomly rebooting

nb that i was Just theorizing in culprit and explanation.
We'll still have top confirm the cause (though the bisection hast now narrowed to the GPU and the other commits don't Look nearly as suspicious)

If this pans Out to be the Offending commit, that's actually "good" because the Problem isn't Just the outfall of some actual fix/Feature Implementation but rather unfortunate target shifting.

Re: System randomly rebooting

Yes, they updated to 6.10.4 but had a sudden reboot still. So back to 6.9.10 which I built locally and it's all good as before.

So keep bisecting I guess

For those who don't wish to wait, downgrade to say 6.9.10 and pin linux till it's fixed in pacman.conf

It's not preferred to downgrade that low. 6.10.2 is the latest kernel that doesn't have the issue. Just use the

downgrade

utility, since it's much faster and easier.

Scratch this.   6.10.2 also has the issue though for me it's not nearly as frequent.    I had another random reboot similar from when I went from 6.9 to 6.10.3.
