[Bug 136814] Re: ndiswrapper invalid buffer

Tue Oct 16 13:42:47 UTC 2007

With 2.6.20-16-server everything works ok.

With 2.6.22-14-server and ndiswrapper 1.43-1ubuntu2 kernel oops (see below).
With 2.6.22-14-server and ndiswrapper 1.49rc1 and 1.49rc3 the wifi dongle can't connect to the AP, so i don't know if once connect it will oops again.

Note that this happens when amule is running, so high network load is
going on... (#147464 again)
