Re: [lwlan-devel] Linux-wlan-ng and xen

Richard,

Thanks for your thoughts. Where can I get hold of this patch from? Is
there an SVN or CVS repo with all the patches in - I'm already running
the FC5 udev patch, now there's this reference counting one too - it
would be nice if I could download a 'clean' copy from somewhere. I
haven't had time to do much in-depth diagnosis  of the problem yet.
Unloading and reloading it didn't work, even if I stopped the xen
service, something somewhere was getting well and truly broken. Since
you mention resume I'll bring up something else odd I've noticed - for
some reason after a resume, my card (a Netgear MA111 USB thingy)
doesnn't pick up and IP address and I have to do an ifdown and ifup to
get it to pick up an address. Any ideas?

Regards
David
