Re: kern/52899: Kernel panic with iwm

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

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
