Attached patch should fix the panic, I should push this into tree
finally..
The dmesg in PR170573 shows some confusing information, the driver is
iwi(4) but the firmware load is for ipw(4), is this some left over from
an older setup? I so, clean up your loader.conf please.
Can you please pull a 9.1-beta memstick image or something and give
this a quick shot? Just so we now that issue still exists on a more
recent system.
The relevant part from the dmesg is basically this line:
iwi0: firmware error
after that, the hardware is dead. We need to figure out why this is
happening, please post more details about your setup and configuration.
Preferably also a the full dmesg with wlandebug 0xffffffff enabled
before above error line is printed.
