[Bug 441204] Re: System hang when I used cisco vpn client and I want to connect to our exchange server with evolution

[utnubu(k)]

Got the same problem with the new kernel (2.6.31-14-generic) but ONLY when using my external wifi card (rtl 8187 chipset)
What I did in terminal to install cisco vpn client to the new kernel:
a) downloaded and extracted vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz
b) patch it with vpnclient-linux-2.6.31-final.diff
c) replace the string const struct net_device_ops *netdev_ops; with struct net_device_ops *netdev_ops; netdevice.h files with:
# sudo sed -i 's/const\ struct\ net_device_ops\ \*netdev_ops;/struct\ net_device_ops\ \*netdev_ops;/' `find /usr/src -name netdevice.h`
d) installing cisco vpn: # sudo ./vpn_install
e) turning off 2nd cpu core with: sudo sh -c 'echo 0 > /sys/devices/system/cpu/cpu1/online' to prevent crash caused by cisco dual core bug
f) start cisco vpn with: # sudo /etc/init.d/vpnclient_init restart   and connect with: # sudo vpnclient connect wlan

Works like a charm for my internal intel gm 45 express chipset.
But when I try with my external wifi Alfa awus036h (realteak 8187 chipset), the whole pc freezes as soon as I press the enter key to establish the connection with my Lenovo R400 laptop.
