The computer (amd64) fails to boot. The init was stuck at the synchronization of the time through the network. This began between 5.16.2 (good) and 5.16.3 (bad.) This continues on 5.16.4 and 5.16.5. Git bisect revealed the following. In this case the nonfree firmwre is not present on the system. Blacklisting the iwflwifi module works as a workaround for now.
6b5ad4bd0d78fef6bbe0ecdf96e09237c9c52cc1 is the first bad commit commit 6b5ad4bd0d78fef6bbe0ecdf96e09237c9c52cc1 Author: Johannes Berg johannes.berg@intel.com Date: Fri Dec 10 11:12:42 2021 +0200
iwlwifi: fix leaks/bad data after failed firmware load
[ Upstream commit ab07506b0454bea606095951e19e72c282bfbb42 ]
If firmware load fails after having loaded some parts of the firmware, e.g. the IML image, then this would leak. For the host command list we'd end up running into a WARN on the next attempt to load another firmware image.
Fix this by calling iwl_dealloc_ucode() on failures, and make that also clear the data so we start fresh on the next round.
