5.10.70 crashing (actually freezing everything)

Support Kernel
1

I recently installed Manjaro on this laptop. The Manjaro iso used: 5.13 which is now eol.

I tried to switch to 5.10.70 and after a few minutes, everything freezed. No keyboard… The only thing that kind of worked was the mouse. I could move it but not click on anything.

This is the only thing I could see on the journal:

Oct 16 18:36:35 dodoite kernel: INFO: task kworker/5:1:72 blocked for more than 122 seconds.
Oct 16 18:36:35 dodoite kernel:       Not tainted 5.10.70-1-MANJARO #1
Oct 16 18:36:35 dodoite kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
Oct 16 18:36:35 dodoite kernel: INFO: task kworker/5:3:488 blocked for more than 122 seconds.

Oct 16 18:37:02 dodoite systemd-coredump[2332]: Failed to connect to coredump service: Connection refused

It doesn’t say which task… No idea.

I’m back on 5.13.19. No problem, so far “rock solid”…

Any suggestion on what to do at this point.

Here’s my inxi

If I’m right, your machine is pretty recent?

A more recent kernel could be better, as newer hardware are better supported with newer kernels.
Could you try 5.14 kernel and check how your system behaves?

If you absoluterly want 5.10 as it’s LTS, more issue digging will be necessary.

I bought the laptop at costco in the spring 2021, but the amd CPU + APU came in late 2019.

Right now, I’m using manjaro/5.14 and it’s currently working, but I’d be more comfortable with an LTS.

I tested my laptop with a live debian 11 bullseye and it uses: 5.10.70. It works w/o any problem. I assume that it either has to do with either a Manjaro configuration or a Manjaro firmware.

Debian backports features and bugfixes from newer kernels, but Manjaro use vanilla kernel, mostly.
