Hi, I got every 5 min or so a error message (with loud beep) in the notification area, any idea what can happen ? I have run a comprehensive memory test from the BIOS (5 hours…) and all is green.

Those appear to be memory or cpu errors – L3 cache

What is the cpu temp?
Have these errors appeared before?
please post the output of inxi -Fzx inside the </> Preformatted text tags from the toolbar above your text entry screen.
Please also run memtest86 on the system to narrow down the error location.

A search for the Syndrome: portion of the error shows several entries about the lenovo thinkpad t14 and z16 series with similar errors.
English Community-Lenovo Community is one of those as is this one https://www.reddit.com/r/thinkpad/comments/vsqlb4/thinkpad_z16_and_linux/

thx very much, you have probably nailed it ! I read all the posts you have referenced. Below is the inxi output.
The problem occurs from the first time I installed Fedora 36 KDE.
How can I check the CPU temp ? output of the fan is cold.
Cant install memtest86 using sudo dnf install memtest86…

This morning I installed latest patches from Fedora and for a while (1 hour for sure) , I did not get back these errors. However, later the machine shutdown failed (stucked), and restarting the t14s leads me to the display of the background image, but no KDE menu… I had to forced shutdown (ctrl-alt tab F2, logging as root and typing “reboot” did not work !!), and then it was OK, but the deaded error reappeared…

So I face a very difficult problem here : should I return the T14s ?? Either

  • I wait for a working patch for firmware, but it can be very long (month, year ???)
  • i return the laptop, but it was otherwise perfect !!! Superb keyboard, screen adequate for me, light, etc. Intel version of t14s are almost 2x the price and the 12th gen are known to be ridiculously hot (toaster…).

What would you do ? I thought about System76 lemur pro, but very expensive, average keyboard with ridiculously small arrow key, POP OS only ( I hate Gnome) and the same *itty Intel 12th gen…

Lenovo is aware of this issue and they will fix it in a future BIOS update. English Community-Lenovo Community

I have the same issue with a different Lenovo AMD 6000 laptop (Yoga 7 14ARB7). Apparently this affects a lot of Lenovo laptops with specific Micron DDR5 RAM.
