I've been having problems with my iwm7260 wifi card since switching to the 11-STABLE/BETA builds where it won't pick up my home network.

After editing wpa_supplicant.conf to try and resolve this, I restarted the network a few times in quick succession and got a panic.

I'm currently on r303628, having the latest changes to iwm by Sean Bruno.

I also experience this panic.

iwm0: hw rev 0x230, fw ver 22.361476.0, address xxxxxxxx

FreeBSD ge73 12.0-STABLE FreeBSD 12.0-STABLE r342149 GENERIC-NODEBUG  amd64

I experienced the issue under 11.x as well.

iwm0@pci0:2:0:0:        class=0x028000 card=0x10108086 chip=0x24fd8086 rev=0x78 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Wireless 8265 / 8275'
    class      = network

This card is also quite unreliable if I increase the channel width on the AP.  Disconnects around an hourly basis with very little info in the logs.
