Re: tcpdump broken after rh9 2.4.20-27.9 kernel upgrade

Hmm,

I updated via up2date and my tcpdump works fine. Also, my old kernel wasn't
removed automatically...
I'm not quite sure that this really helps but at the very least you know that
different things are being seen :-(

Do you have other systems that this has happened to or is this the only one?

HTH,
