System randomly rebooting

fish4terrisa-MSDSM · 2024-08-23 08:01:15

For anyone experienced random reboots with ryzen 9 7900 series,maybe try this cmdline:

rcu_nocbs=${your cpu threads, I forget the wiki page where i see it, mine is 0-31} processor.max_cstate=5 pci=nomsi

and open the AMD Precision Boost Overdrive(enable,not mark it in auto state)
I got random reboots with a ryzen 9 7940hx laptop,and after taken this fix, all reboots are gone. Maybe these will also work for you :-)

https://wiki.archlinux.org/title/Ryzen#Random_reboots and that's not the problem in this thread at all.

The fix just reached mainlined in https://git.kernel.org/pub/scm/linux/ke … d4bfb82b4b. Hopefully it will be in one of the next few upstream stable releases.

6.10.7 was released and it contains the patch https://git.kernel.org/pub/scm/linux/ke … a05a293e4b .

Big thanks to all who helped get this resolved.

I just experienced another reboot on 6.10.7-zen after ~25hrs uptime.

I'm running 7950x3d on an Asus ProArt x670e. I've been following this thread since I noticed the same problem about a month ago. Since then, I decided to stick with 6.10.1-zen, which has run fine for weeks.

I have also swapped the PSU, memory, CPU, and motherboard and confirmed this is not a hardware issue.

So, is there anyone else experiencing the same issue?

Of course it is: https://duckduckgo.com/?q=ryzen+idle+reboot

If you really think it's not a hardware problem, tell us which commit introduced the variable that causes your system to reboot itself.

https://bbs.archlinux.org/viewtopic.php … 4#p2191794 - this thread revolves around a driver patch that certainly seems to promote the fatal condition.
@yu17
a) The zen kernel isn't somehow for Ryzen, the naming is conincidental. Do you still have the problem w/ the vanilla 6.10.7 kernel?
b) did the frequency change w/ 6.10.7?
c) did the issue exist w/ 6.10.2? Does downgrading to it fix it for you?
d) nb. that if/since you've swapped out huge parts of the HW, data collected with the old HW setup is no longer applicable

for what it may count, I am using 6.10.7 vanilla since it was released on arch repos and i did not encounter any forced reboot yet. I used the laptop at least 8/10 hours per day but i did shut it down several times, so i cannot speak about 25hours uptime (given that 25hours uptime meant continued uptime).
I will let you know if i encounter any problems.
