Public bug reported:
The default remove rule in /etc/modprobe.d/iwlwifi.conf fails on Wi-Fi 7
(802.11be) hardware because it only greps for iwlmvm, iwldvm, and
iwlwifi, omitting iwlmld.
Root Cause:
When modprobe -r iwlwifi or modprobe -r iwlmld is called, grep finds no matches
on systems using iwlmld, passing an empty string to xargs /sbin/rmmod. This
causes rmmod to return exit status 1 with rmmod: ERROR: missing module name,
breaking systemd sleep/suspend hooks.
Proposed Fix:
Add iwlmld to the grep patterns and passing --no-run-if-empty (-r) to xargs:
remove iwlwifi (/sbin/lsmod | grep -o -e ^iwlmld -e ^iwlmvm -e ^iwldvm -e
^iwlwifi | xargs --no-run-if-empty /sbin/rmmod)
