Title:
linux-firmware package breaks iwlwifi
Status in linux-firmware package in Ubuntu:
New
Bug description:
This package version works:
20230919.git3672ccab-0ubuntu2.1
This one causes firmware SW errors and resets - breaking wifi in
iwlwifi driver:
20230919.git3672ccab-0ubuntu2.9
I am running 23.10 with "Tiger Lake PCH CNVi WiFi" and after upgrade
to ...2.9 of the linux-firmware package, I saw many errors that begin
like this in syslog:

Downgrading to ..2.1 version of linux-firmware fixes wifi and I see no
errors.
