[main@main ~]$

so I was playing satisfactory - never had issues with it - and it crashed twice today - but was fine again after reboot
played for some time - then the game crashed again - and before I clicked on play again my system just hard rebooted (hence my journal just ends)
I rebooted into multi-user.target and checked temps - but all were good (cpu, gpu, ram all around 60-80 C)

can anyone get a clue what might happened?

Undervolt status on both CPU/GPU?

cryptearth · 2025-04-08 03:57:46

both cpu and gpu are stock without any modifications
the only "oc-feature" enable is xmp/docp on ram - but this is only a slight boost from jedec base of 3.200 to 3.600 (before I bought it I asked for advice and most recommended rather slow speed and not so agressive timings for stability over high speed and tight timings - hence I have rather slow ram) and my specific kit is on the verified list
given from the error log of the game crash I would see that as the cause - something similar happend to me roughly about 15 years ago when my system out of nowhere raised some virus alerts - which turned out a ram fault in the area where the anti-virus had loaded
so - could it be just some random bit-flip caused an otherwise non explainable crash?
the system runs fine so far again - so I doubt it's anything persistent - but running full memtest and gpu stress will take days for something maybe just a random cosmic ray

CPU: AMD Ryzen 5 5600 (12) @ 4.47 GHz

is otr, https://wiki.archlinux.org/title/Ryzen#Random_reboots but still disable XMP

cryptearth · 2025-04-08 09:08:01

@Seth
I will give it a shot an run a full system load test. Do you think a memtest would be required? Or does this looks more towards a CPU issue?

seth · 2025-04-08 14:38:55

Or does this looks more towards a CPU issue?

Ryzens are notorious for this, but the problem isn't maximum load but shifting the load between cores.
I'd still disable XMP, if it still happens (what's likely) you
a) know it's not the RAM
b) the RAM won't get in the way of mkitigating this (as a pot. secondary issue)

oof

I had two kinds of crashes, curious about the difference

mce: [Hardware Error]: Machine check events logged
[Hardware Error]: System Fatal error.
[Hardware Error]: CPU:8 (19:21:2) MC0_STATUS[-|UE|MiscV|-|PCC|TCC|SyndV|-|-|-]: 0xbaa0000000160809

[Hardware Error]: Load Store Unit Ext. Error Code: 22
[Hardware Error]: cache level: L1, mem/io: IO, mem-tx: GEN, part-proc: SRC (no timeout)

vs

mce: [Hardware Error]: Machine check events logged
[Hardware Error]: System Fatal error.
[Hardware Error]: CPU:13 (19:21:2) MC5_STATUS[-|UE|MiscV|AddrV|PCC|TCC|SyndV|-|-|-]: 0xbea0000001000108

[Hardware Error]: Execution Unit Ext. Error Code: 0
[Hardware Error]: cache level: RESV, tx: GEN, mem-tx: GEN

More specifically the difference between

[Hardware Error]: Load Store Unit Ext. Error Code: 22
[Hardware Error]: cache level: L1, mem/io: IO, mem-tx: GEN, part-proc: SRC (no timeout)

and

[Hardware Error]: Execution Unit Ext. Error Code: 0
[Hardware Error]: cache level: RESV, tx: GEN, mem-tx: GEN

When undervolting the last one seems more common.

I've checked my last about dozen journals and none had such "hardware error" lines
also it's the very first time my current hardware had such a hard fault - and it's already at least 2 1/2 years old (+ for how long it was on the shelfs)
the only thing I suspect is my power supply which is at least 10+ years now - guess it's time for a new one - as its the cheapest part to replace

qu@rk · 2025-04-09 10:00:10

Your CPU+GPU should draw a max of 330W or so under synthetic loads, less in gaming.
You could also disable C6 states and/or XMP and see if it still happens. Though a dying PS could always be the culprit.

seth · 2025-04-09 14:44:53

@qu@ark, your error are perfectly in line w/ the known ryzen issues, see the troubleshooting link.
Undervolting does *not* help here at all, you're supposed to feed *more* voltage to the cores (what will inherently heat them up and prevent aggressive single-core boosts)

@cryptearth, the AMD sitaution is aggrevating, s it's "normal" that it only shows up with time - w/o any data this is your best shot, unless you know that it's more likely to happen under maximum load (and your PSU being on the edge of the total system demands anyway)

If you can run windows on the system, corecycler is a pretty reliable way to trigger the issue.

qu@rk · 2025-04-09 17:30:19

Yeah I know I'm doing it on purpose (very low undervolting) trying various things. I should disable C6 as well as I didn't so far, I'm stingy that way. I did recommend others turn it off and seemed to have worked for some of them. But with C6 off I get like extra 2-3W power consumption at idle.

cryptearth · 2025-04-09 20:39:10

so I ran corecycler along with furmark for about 3 hours (I guess only a concurrent memtest could had put more stress on the system) - and all was stable and fine
as the issue I encountered happend pretty much after the game crash I guess it was the game or the crash of it which caused some random chain of events resulted in a hard reset - maybe even triggered some kernel panic that was not recorded into the logs
nevermind - gonna mark this as solved as it was a one-time - but I'll keep in mind to maybe look out for a new power supply due to its age
