Description of problem: When attempting to shutdown, suspend, or unplug the PCMCIA network card the following error is logged repeatedly: kernel: unregister_netdevice: waiting for eth0 to become free. Usage count = 2 The network card in question is a Lucent Orinoco 802.11b card. I have not yet managed to work out how to get the machine to shut down cleanly. Version-Release number of selected component (if applicable): kernel-2.4.21-20.1.2024.2.1.nptl kernel-2.4.22-1.2049.nptl kernel-2.4.22-1.2051.nptl How reproducible: Always. Steps to Reproduce: 1. Use an Orinoco 802.11b card to connect to the network. 2. Attempt to shutdown the system. Actual results: When attempting to shutdown the pcmcia subsystem, the following messages is printed repeatedly, roughly once per second: kernel: unregister_netdevice: waiting for eth0 to become free. Usage count = 2 Expected results: The system should shutdown cleanly. Additional info: Full text of syslog entries before failure: cardmgr[498]: executing: './network stop eth0' modprobe: modprobe: Can't locate module tun6to4 /etc/hotplug/net.agent: Net unregister event not supported. modprobe: modprobe: Can't locate module char-major-10-134 kernel: unregister_netdevice: waiting for eth0 to become free. Usage count = 2
