Following some advice I read on the net, resetting bios to default settings seems to help. So I don't see this freeze anymore. I haven't investigated further. I've got 2 more devices, but these aren't much help.. first: wi0: <NEC Wireless Card CMZ-RT-WP> at port 0x100-0x13f irq 20 function 0 config 1 on pccard0 wi0: Sorry, this card is not supported (type 2, firmware ver 704) device_attach: wi0 attach returned 45 second: an0: <Cisco Systems 350 Series Wireless LAN Adapter> at port 0x100-0x13f irq 20 function 0 config 5 on pccard0 : record length mismatch -- expected 194, got 196 for Rid ff10 : record length mismatch -- expected 192, got 200 for Rid ff00 an0: got RSSI <-> dBM map an0: supported rates: 1Mbps 2Mbps 5.5Mbps 11Mbps an0: Ethernet address: 00:0b:fd:7f:ae:3d an0: [GIANT-LOCKED] an0: record length mismatch -- expected 194, got 196 for Rid ff10 an0: record length mismatch -- expected 194, got 196 for Rid ff10 an0: record length mismatch -- expected 194, got 196 for Rid ff10 an0: record length mismatch -- expected 194, got 196 for Rid ff10 I'm struggling to make Aironet 350 work.
