Description

Hello bugs@,

After a fresh install of DragonFly 2.9-dev on a Lenovo THINKPAD R500 and
a basic configuration of the
iwn module (cf. man iwn), I tried to do an : ifconfig iwn0 up .

However, by doing this, I only get a kernel panic...

I attached a coredump file to this mail.

If you need more informations or details, feel free to ask.

Please try this patch as well. This should be applied after applying
the original patch.
