Bullseye wi-fi. I have to restart NetworkManager every 5 minutes
Hi,
$ uname -a
Linux t440 6.0.0-0.deb11.6-amd64 #1 SMP PREEMPT_DYNAMIC Debian
6.0.12-1~bpo11+1 (2022-12-19) x86_64 GNU/Linux
$ cat /etc/debian_version
11.2
For some reason, every time I am connected to wifi, pages can't load
after 5 minutes of activity and I have to restart NetworkManager to get
them back.
$ ping 8.8.8.8 # nothing
# dmesg -C # clears the buffer
# systemctl restart NetworkManager
$ ping 8.8.8.8 # it works
$ dmesg

I googled the above and this looks like a known kernel bug affecting old
Thinkpads.
I have the latest kernel from Bullseye backports. I don't want to
upgrade yet.
Any clue?
