I'm not actually sure just what you mean by removing the wifi driver, but I just now tried moving the iwlwifi firmware out of /lib/firmware, then booted 5.6.4 as before (with "ignore_loglevel initcall_debug" and with the CDROM still detached), and of course there was now no wireless interface. I started X, Emacs, Firefox (of course with no internet), VLC, used them a bit then closed them all, then called `shutdown -h now' and the message output was essentially identical to what I posted previously (but of course without "iwlwifi 0000:02:00.0: shutdown") and the machine did not power off. So if this was the test of removing the wifi driver, then it made no difference. Steve Berman
