Title:
22.04LTS firmware does not work for an iwlwifi 802.11 interface that
did work under 20.04LTS
Status in linux package in Ubuntu:
Incomplete
Bug description:
I just updated in place (no new harddrive, no new partitions) from 20.04LTS
to 22.04LTS. Everything worked except that there is a firmware loading
diagnostic (along with a separate failure to compile the VMWare kernel support
-- but that may be a VMWare issue, not Ubuntu). Thus, the 802.11 hardware is
NOT "seen" by the kernel, etc. (I am using bluetooth to Android phone to our
802.11 network to get to the Internet right now -- not the laptop 802.11). The
relevant section of the dmesg log seems to be: [ 30.805966] kernel: iwlwifi
0000:3d:00.0: Failed to load firmware chunk!

and more. The machine is a HP Zbook G2 that had no issues with Ubuntu
20.04LTS. Any help would be appreciated. Would it work to downgrade
the firmware .deb to 20.04LTS or would this be not compatible with the
current 22.04LTS production kernel or environment. If downgrading
would work, please provide "detailed" instructions (e.g., the apt
command invocations to use).
