[Mohegan (jack-mohegan)]

I have the same problem. The system freeze with the 6.5.0-25 kernel and intel BE200 but it is OK with 6.5.0-21 kernel.

I have an other issue with Wifi 7 MLO. It doesn't work at all !

Status changed to 'Confirmed' because the bug affects multiple users.

Forum post with someone else with same issue:

https://askubuntu.com/questions/1507282/ubuntu-22-04-4-wifi-became-unstable-after-some-system-update-and-maybe-install

[Mohegan (jack-mohegan)]

With Mantic, the connection freezes after some times with 6.5.0-21 kernel...

So, I switched to Ubuntu 24.04 / Noble for testing. The connection is much stable (but not MLO support).

[Marcelo Vanzin (vanzin)]

I'm not sure the problem I'm having is exactly the same, but I also can't get any kernel after 6.5.0-21 to properly boot up on my laptop with an Intel wifi card.

I'm attaching the portion of kern.log where a bunch of kernel worker tasks are reported as timed out; that happened, IIRC, after I tried to shut down the system by hitting the power button. The system wasn't really usable since most processes weren't able to start, so I couldn't really do a lot of investigation. Even trying to do "sudo blah" or just "ifconfig" would hang indefinitely.

If it's any help, I have a bunch of options set for the Intel wifi driver:
options iwlwifi power_save=0
options iwlmvm power_scheme=1
options iwldvm power_scheme=1
options lwlwifi bt_coex_active=enable

[Eric Burns (ezyk)]

Issue still exists with 6.5.0-26

[Jacek Kowalski (kowjack)]

I probably have the same issue: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-6.5/+bug/2058808
Very frustrating.
