So basically we can say that at least several systems with multiple adapters are affected, and no-one has yet reported a system with a single adapter being affected so far as I can tell. But not *all* multiple adapter systems are affected. We don't know what the difference is yet. Still, safest thing is just to assume that if you have a multiple adapter system you may be affected. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
