Bug Description

Firstly, I have a fully working ndiswrapper configuration with the 64bit windows
netbc564 driver. This problem relates to what happens when such a configuration
is present and I reboot.

If I reboot with a running configuration, the machine slows to a crawl to boot,
the 'events/0' process takes up 90%+ CPU and it can take 20minutes or more to
boot (this is a 64bit 2.2GHz machine!). During boot there is a kernel message
indicating that something is hogging resources. This renders the machine unusable.

The workaround is to rip-out the configuration on boot time, by modifying
/etc/init.d/linux-restricted-modules-common which is run VERY early on with the

> /usr/sbin/ndiswrapper -e netbc564 >/dev/null

This causes a few errors in the log when the the wireless network interface is
started but stops the condition from appearing. In order to 'enable' the
interface I've written a startup script, but haven't been able to get it 'auto
loading' without causing this problem, so its a post-boot, post-login solution,
which actually works fine, so I only enable wireless when I need it, saving power.

Something is going nuts in ndiswrapper during the initial module load and
configuration of devices...

Ill add my startup script for info, it took me a while to work out what I had to
do to get it running
