https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291120 Bug ID: 291120 Summary: iwlwifi: iwl_opmode_register panic Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: wireless Assignee: bz@FreeBSD.org Reporter: bz@FreeBSD.org CC: wireless@FreeBSD.org Blocks: 273620 Flags: mfc-stable15? I believe we had a similar issue in the beginning of mvm. Interestingly I had not seen this on any other of my machines (some of which have three iwlwifi cards in them currently) including BE200 which is the mvm/mld crossing child. Now that the code got split off and partially duplicated it might be good to look through all the FreeBSD #ifdefs and see what also applies to mld and then get the not-really-FreeBSD-specifics upstreamed possibly for 6.19 still.
