https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263505 Bug ID: 263505 Summary: vlan on wlan kernel panic Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: leres@freebsd.org Created attachment 233427 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=233427&action=edit kernel stack trace A friend (Jeff Anton) reported a kernel crash when trying to configure a vlan on a wlan interface under 13.0. I did some testing with a spare amd64 box and was able to reproduce the crash with both 13.1-RC4 and 12.3-RELEASE-p5. The rc.conf from my test setup looks like this: hostname="test.alameda.xse.com" sshd_enable="YES" dumpdev="AUTO" keymap="us.ctrl" wlans_iwn0="wlan0" ifconfig_wlan0="WPA SYNCDHCP" vlans_wlan0="vlan0" create_args_vlan0="vlan 1234" wpa_supplicant="YES" (This assumes a valid wpa_supplicant.conf.) After booting and successfully joining wifi issuing: ifconfig vlan0 192.168.1.1 results in a "page fault while in kernel mode" panic. Kernel stack trace attached (13.1-RC4). -- You are receiving this mail because: You are the assignee for the bug.
