Hello Holger Yesterday i had a look in the upstream kernel tree. Can you please also look at the commit:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/net/wireless/intel/iwlwifi?h=next-20220215&id=bea2662e7818e15d7607d17d57912ac984275d94 This commit contains a fix, introduced here: Fixes: ab07506b0454 ("iwlwifi: fix leaks/bad data after failed firmware load") After some time with Google, this commit ab07506b0454 results in exactly this behaviour i saw at my system. And the new commit fixes this issue. If i understand it right: Failed loading firmware causes to the trap by reading memory after it was freed. Do you think, this commit can be cherry-picked to sid? Best regards Bernhard
