Bill: didn't you fix this 2 days ago ? Yes, it's fixed in later kernel-pcmcia-cs (-8 or -9 or so.) |
Pcmcia ethernet support is broken in Roswell2. The problem is in following part of /etc/pcmcia/network: 'stop') # # We don't do anything here either. We get a hotplug event when # the ethX device is unregistered too... # ;; It's wrong idea that physical removing of pcmcia card is a hotplug event. Actually module removing is a hotplug event. But cardmgr is unable to remove module, because module is busy with active eth interface. Look what happenes whan I physically remove xircom ethernet card: Aug 22 11:05:13 localhost cardmgr[812]: shutting down socket 0 Aug 22 11:05:13 localhost cardmgr[812]: executing: './network stop eth0' # interface must be deactivated by './network stop eth0' here Aug 22 11:05:13 localhost cardmgr[812]: executing: 'modprobe -r xirc2ps_cs' Aug 22 11:05:14 localhost cardmgr[812]: + xirc2ps_cs: Device or resource busy Aug 22 11:05:14 localhost cardmgr[812]: modprobe exited with status 1 As a result, module with busy flag Module Size Used by xirc2ps_cs 11488 1 will hang forewer untill you type 'ifconfig eth0 down' and 'rmmod xirc2ps_cs' manually. Additionally, if you insert card again, it will become eth1.
