It only says: # /usr/local/etc/rc.d/iwi0 start iwi0: could not allocate firmware DMA memory iwi0: could not load main firmware And can't bring the card up again. Even unloading the kernel module fails: # kldunload if_iwi iwi0: detached # kldload if_iwi iwi0: <Intel(R) PRO/Wireless 2200BG> mem 0xe0200000-0xe0200fff irq 22 at device 2.0 on pci2 iwi0: Ethernet address: 00:0e:00:00:00:00 (masked) iwi0: Please load firmware # /usr/local/etc/rc.d/iwi0 start iwi0: could not allocate firmware DMA memory iwi0: could not load main firmware ifconfig iwi0 down/up has no effect as well. The only solution seems to reboot. This problem seems to be more frecuent when the net is under load. Since it seems to be a common problem, and the card can get a fatal error any time, the driver should try to restart the card, and only print a warning that got a fatal error. Note: I had similar problems with 5.4, but ifconfig iwi0 down/up worked to get the card back up, and after several down/up's I got kernel panics (but I haven't got that far with 6.0). >How-To-Repeat: Use the wireless conn, for some time After the error try to bring the card back up >Fix: >Release-Note: >Audit-Trail: >Unformatted:
