 Hi,
 I'm not developer, and maybe I'm missing something, but I started to boot
 my laptop. As expected, kernel panic occurred.
 
 ...
 boot device: sd0
 root on sd0a dumps on sd0b
 root file system type: ffs
 kern.module.path=/stand/amd64/8.0/modules
 iwm0: hw rev 0x210, fw ver 22.361476.0, address 3c:f8:62:xx:xx:xx
 panic: kernel diagnostic assertion "if_is_deactivated(ifp)  ||
 IFNET_LOCKED(ifp)"
  failed: file "/usr/src/sys/net/if.c", line 1819
 fatal breakpoint trap in supervisor mode
 trap type 1 code 0 rip 0xffffffff80224d95 cs 0x8 rflags 0x246 cr2

 Stopped in pid 0.82 (system) at netbsd:breakpoint+0x5:  leave

 Then, I pressed t. The output is below:

 I hope this output would be helpful. If not, can you explain what should I
 do?
 
 Thanks in advance,
 Mustafa Dogan
