[Bug 152448] After reboot, ndiswrapper stops working

[gonetil]

Public bug reported:

I have a toshiba A215-S4747 laptop, with a Atheros 5006 wifi card. I am using ubuntu 7.10 RC x64.
I have installed wifi with ndiswrapper since Mad-wifi drivers did not work.
After installing ndiswrapper and the winxp64 driver, I reboot the system and everything works perfect. I can connect to secure and non secure wireless networks, get IP by DHCP and so on. But once a reboot the system, I cannot connect to any wifi network (wired networks have no problem at all).
I can scan the air, and I can see all networks available, but it is impossible to connect to any of them (insecure, wep, wap, wap2, etc).
I know how to make it work again:
uninstall windows driver, uninstall ndiswrapper. 
Reboot.
Install back ndiswrapper and winxp driver. 
Set ndiswrapper to load on startup. 
Reboot. 
After all this, the wifi card works again perfectly. But if I reboot, I get the same error, although I keep all my network configuration, it just don't work. Ath_PCI module is blacklisted.

More information:
When everything works fine,  ifconfig command shows:

and dmesg | grep ndiswrapper returns

When things go wrong,  dmesg | grep ndiswrapper returns:

Strangelly, MAC address has only zeros (I don't know if it is important or not)
Finally, iwconfig shows
