@bac0n

What distro do you use?
It seem only 8812AU users are affected, I cannot reproduce this issue with 8822BU on my Arch Linux (kernel: 6.12.4-arch1-1).

[bac0n]

$ uname -a
Linux betazoid 6.12.4-2-amd64-betazoid #1 SMP PREEMPT_DYNAMIC Tue Dec 10 18:05:57 CET 2024 x86_64 GNU/Linux # (vanilla kernel.org)

$ cat /etc/debian_version
trixie/sid

I will try a debian kernel, and which git commit introduct the crash.

[dubhater]

Ah, sorry about that. It should be fixed now.

[bac0n]

yep, fixed, thanks :)=
