[Solved] Soft lockup due to ethernet connection
I noticed my system hangs after I switch off wifi while having connected ethernet cable.
Here is the relevant journalctl log:

I found the same issue with kernels linux 6.8.6.arch1-1and linux-lts 6.6.27-1.
---
Apparently there was an issue related to systemd bluetooth.service.
I found a pacnew file for /etc/bluetooth/main.conf with the default option `autoenable = true`.
I had it set to `autoenable = false`, so commenting this line solved the issue.

Re: [Solved] Soft lockup due to ethernet connection
I'm having a similar issue, only it happens when I plugin an ethernet cable.
Here's the `journalctl -k -b -1`:

Apr 25 16:38:27.013951 x kernel: watchdog: BUG: soft lockup - CPU#3 stuck for 26s! [kworker/3:1:79]I took a look at /etc/bluetooth/main.conf like suggested above, but that was just the default configuration (I never touched that file)
However I found this kernel bug-report:
Bug 218740 - 6.8.6 BUG: scheduling while atomic: kworker/5:0/84234/0x00000002 (e1000e?)
There is a patch linked in that bug. I followed the wiki instructions in the Kernel/Arch Build system to incorporate
the patch into the linux kernel and it solved my problem.
They also mention that the issue seems to be with kernels >=6.8.5, which is curious because found this issue also with linux-lts-6.6.27-1.

I notice the same issue with kernel 6.8.8.
The only way around is to first disconnect wifi, then connect the ethernet.
The bug appears when you connect the ethernet while the wifi is still on.

Re: [Solved] Soft lockup due to ethernet connection
@rsaavedra if building the kernel yourself is preventing you from testing the proposed fix you can find a prebuilt kernel with it applied in https://bbs.archlinux.org/viewtopic.php … 1#p2165871
