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.
