Hi everyone,

ever since I switched to Arch about two months ago, most applications segfault multiple times a day. There doesn’t seem to be any pattern for the crashes, sometimes it’s even happening while idling (e.g. reading a news article).

Things I’ve tried without any luck so far:

  • Running Firefox in safe-mode without any extensions
  • Switching from regular to LTS kernel
  • Disable Hardware Acceleration in Firefox
  • Change RAM speed and timings
  • Run Memtest successfully
  • Replace entire RAM with a new certified kit
  • Use only a single RAM slot
  • Apply Ryzen fixes (iommu=soft, limit c-states)
  • Use only a single CPU core (maxcpus=1)
  • Downgrade Nvidia driver to 535xx
  • Use Nouveau instead of the nvidia driver
  • Use Openbox instead of KDE
  • Disable zswap and THP

Here’s full journalctl from a day where both Spotify and Firefox crashed at the end, a few seconds after each other:

Some more info about my system:

  • Ryzen 5 3600X
  • MSI B450M PRO-VDH Max
  • 32GB RAM @ 3200MHz
  • Geforce RTX 2070 SUPER (using nvidia-dkms)
  • Plasma 5.27.10 on X11

I’m pretty sure that it’s not hardware related, because I’ve booted up a Debian 12 live image where everything ran for several hours without a crash. But it seems to be Arch related, as I also booted up a fresh EndeavourOS live image (so basically Arch), where applications also randomly segfaulted. Any idea why everything works fine on Debian but not on Arch? Debian uses the 6.1 kernel, which I already tried, so that’s not it.

Let me know if you need any more information that might help solve this issue. Thanks!

Edit [solved]: It looks like disabling PBO in the UEFI/BIOS did the trick. The strange thing is, after enabling it again, it’s still not crashing again. Someone suspected that the MoBo default/training settings were faulty, so I guess this was a very rare case here. That’s probably why it took so long to find a solution. Thanks everyone for helping me out!

    Could be a defective library that’s used by many apps. Glibc, etc. That said, if something like this is that broken, others should be complaining about it too.

      One crash was in libxul and the other in libcef I doubt this is a specific lib

        This is a good idea, but they probably need to figure out which lib is shitting the bed first. There’s too many libs to try otherwise.

        Maybe a corrupt download/copy of a library… Try a reinstall of say glibc ?

        Doesn’t explain why it also crashes in an EndeavourOS live image…
