[-- Attachment #1 --] After the ssh vulnerability was announced, I updated my kernel. After completing the upgrade, it crashed when the system was booted. All stack dumps showed lots of drm points on hte stack. So, I tried removing the i915kms from the kld_list in rc.conf. The system booted and started the wifi without crashing. When I loaded i915kms manually, the system froze. I still am wondering if there is some collision in the lkpi when the drm driver on Alder Lake is present and the wifi starts. While I failed to get much saved during the multiple reboots, all showed the crash after wpa_supplcant started. Is this remotely possible or just a coincidence? I have rolled my system back to 06c083f79dd7 (Dec. 2) just to get it running with both graphics and wifi. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 [-- Attachment #2 --] <div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">After the ssh vulnerability was announced, I updated my kernel.
