How to find an hardware error (System freeze, automatic reboot)


this is my first post so I hope its ok here.

I have the following problems once/twice a day - only hard reset possible

  • system freeze or
  • system automatic reboot

the log says: mce: [Hardware Error]: Machine check events logged

It only happens when using Browser (Firefox, Chrome) or Citrix Workspace.
I play online games for hours and it never happens.

How can I find out if it is a hardware problem and what is wrong.
(Problem also occur on diffrent kernels and Nvidia drivers, fedora 36, Linux Mint, Manjaro)

thank you in advance

You seem to have ruled out most software, although different linux versions may all use the same buggy firmware blob. Consider trying nouveau.

Concentrate first on easily fixable problems: cables, connectors, power, and memory. Search here for advice on memtest86+ – if you are using UEFI secure boot you need a recent version.

I live in a area surrounded by ocean and have colleagues who take computers to sea on research vessels, so connections start to fail after a few years. The big name-brand vendors have improved their connectors, but sometimes poor connectors end up in high-end gear. Now that automobiles depend on computers, auto parts stores sell “contact enhancer”. Just reseating connections after inspecting them for signs of corrosion often gets things working for a short time – contact enhancer helps to keep connections good for a long time.

The easy way to check a power supply is to swap with a known good unit. Modern manufacturing tolerances are such that power supplies often fail just after end-of-warranty. I always buy a 2nd laptop power supply, easier now that many laptops can use USB-C power.


i have found a solution for the freeze problem = disable C-State in Bios
ASUS UEFI Bios > Advanced\AMD CBS > Global C-state control = Disabled
ASUS UEFI Bios > Advanced\AMD CBS > Power Supply Idle Control = Typical Current Idle

Additional Information:
It seems there is a problem with AMD Ryzens and the C-State. See Bugzilla and Archwiki

Before I changed the Bios settings I got this error message with journalctl now it seems fixed.
