Re: New iwlwifi firmware for testing in main

Hey Bjoern,

You were asking for an update from me on this ticket https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263613, this is the same issue and you can reproduced this by setting a static IP on the interface and then you can do a 'service netif wlan0' multiple times in sequence, it should crash pretty soon.

If I replace DHCP with a fixed address it panics as before. That is interesting. I'll try to repro that next week. > Apparently this happens as soon as the device associates with an AP. According to the log it didn't associate yet when the firmware crashed. Given this is a 9260 this looks like a bug we fixed about 6-ish weeks ago. Is this a 14-CURRENT or an up-to-date stable/13?
