You can peraps find more information on this thread: http://lists.freebsd.org/pipermail/freebsd-current/2009-March/004521.html >How-To-Repeat: By setting a country value to an iwn card. >Fix: This problem can be fixed by do not seting the country value: In my case it was replacing: ifconfig_wlan0="country FR WPA DHCP" by: ifconfig_wlan0="WPA DHCP" But, this workaround generate a second problem on my laptop: It crash my FreeBSD during startup (without generating a crash dump file), that is (manualy write down) : Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault virtual address = 0x28 fault code = supervisor read data, page not present instruction pointer = 0x8:0xffffffff8044b253 stack pointer = 0x10:0xffffffffe4002ca20 frame pointer = 0x10:0xffffffff.4002cb10 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrrupts enabled, resume , IOPL = 0 current process = 12 (swi4: clock) [thread pid 12 tid 100007 ] stopped at igmp_fasttimo+0x296: movl 0x28(%r14), %eax I need to reboot in single mode and comment the iwn0 configuration line in rc.conf for using my system again. But once booted, In can manually configure the iwn0 card without crashing the kernel. I think that this igmp crash with wifi is reported in this actual thread too: http://lists.freebsd.org/pipermail/freebsd-current/2009-March/004530.html Peraps that I meet a second kernel bug :-) >Release-Note: >Audit-Trail: >Unformatted:
