Hi,

I seem to have hit a bug with the wireless card driver of my laptop.
This happened twice already, my laptop became unresponsive and I
couldn't issue any sudo commands. After hard rebooting the laptop I
see this entries in the syslog:

Sep 10 14:51:50 user-thinkpad kernel: mt7921e 0000:03:00.0: driver own failed
Sep 10 14:51:51 user-thinkpad kernel: mt7921e 0000:03:00.0: driver own failed
Sep 10 14:51:51 user-thinkpad kernel: mt7921e 0000:03:00.0: chip reset
Sep 10 14:51:53 user-thinkpad kernel: mt7921e 0000:03:00.0: driver own failed

This is my network card:
user@user-thinkpad:~$ lspci | grep -i mt7921
03:00.0 Network controller: MEDIATEK Corp. MT7921 802.11ax PCI Express
Wireless Network Adapter

after that the kernel seems unable to get cpu time:

I want to use the reportbug feature but I don't know which package I
should enter. Anyone else having similar issues?
My system settings: Linux version 5.18.0-4-amd64
(debian-kernel@lists.debian.org) (gcc-11 (Debian 11.3.0-5) 11.3.0, GNU
ld (GNU Binutils for Debian) 2.38.90.20220713) #1 SMP PREEMPT_DYNAMIC
Debian 5.18.16-1 (2022-08-10)
The driver is in Linux kernel so if you want to create a bug report it should be against Linux package (5.18.0-4-amd64 in your case).
By the way where did you get this kernel from - from backports or are you using Debian testing or unstable. In case of testing/unstable version 5.19 is available so you can try with newer kernel. 

Kind regards
Georgi
