Hi Nazira,

Thanks for the report and the complete pstore log.

Could you try to reproduce the issue by following the steps described
in:

  https://github.com/ValveSoftware/steam-for-linux/issues/8003

If the problem occurs again, please identify the processes owning the
CContentUpdateC and CHTTPClientThre threads.  While they are running,
please provide the output of:

  ps -eLo pid,tid,ppid,comm,args | \
    grep -E 'CContentUpdateC|CHTTPClientThre'

For each matching PID, please also provide:

  readlink -f /proc/<pid>/exe
  tr '\0' ' ' < /proc/<pid>/cmdline
  cat /proc/<pid>/maps

As the final fault attempted to execute an NX-protected address while
CPU 10 was running the idle task, please also test with the BIOS
defaults, including disabling any EXPO/XMP, overclocking, or
undervolting settings, and run a memory stability test.

Regards,
Yunseong Kim
