Hi everyone,

ever since I switched to Arch a 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!

    Can you enable core dumps and get stack traces? From there you should be able to figure out which shared library is broken.

      Uhm, isn’t that what can be found at the end of the journalctl log I posted? Or are you talking about something different?
