I've seen this on an Aironet 350, RELENG_6 from near the start of September: an0: <Cisco Systems 350 Series Wireless LAN Adapter> at port 0x100-0x13f irq 11 function 0 config 5 on pccard1 an0: got RSSI <-> dBM map an0: supported rates: 1Mbps 2Mbps 5.5Mbps 11Mbps an0: Ethernet address: 00:40:96:50:25:19 an0: [GIANT-LOCKED] I've noticed this problem happens more at $ORKPLACE (which has a somewhat quirky radio environment, where I keep getting disassociated and reassociated to a couple of nearby APs) than at home (one AP). Not sure how significant that is. I don't use suspend/resume on this machine, which is a ThinkPad T21. > Here's what I get on insertion: > an0: <Cisco Systems 340 Series Wireless LAN Adapter> at port=20 > 0x2000-0x203f irq 11 function 0 config 5 on pccard1 > an0: 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: 00:40:xxxxx > an0: [GIANT-LOCKED] >=20 > When net connections start hanging, this is ifconfig: > an0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 > inet6 fe80::xx:xx:xx:xx%an0 prefixlen 64 scopeid 0x4 > inet 10.0.xx.xx netmask 0xffffff00 broadcast 10.0.xx.255 > ether 00:40:xx:xx:xx:xx > media: IEEE 802.11 Wireless Ethernet autoselect > status: no carrier > ssid 1:myssid channel 6 > stationname "" > authmode OPEN privacy ON deftxkey 1 txpowmax 0 rtsthreshold 0 > roaming DEVICE >=20 > And dmesg says: > an0: xmit failed > an0: device timeout I've seen this dmesg output at this point.
