Colin, it's for you ?

Comment 2 Colin Guthrie 2011-10-30 12:01:17 CET

Does this still happen with latest kernel+PA in Cauldron? It would be nice if we didn't have to investigate too heavily as this has the potential to be a real pain to track down.

Comment 3 Marja Van Waes 2012-02-01 07:49:11 CET

Pinging, because nothing has happened with this report for more than 3 months, it still has the status NEW or REOPENED.

Comment 4 Herbert Poetzl 2012-02-01 07:53:59 CET

haven't had the chance to test on that system since, and I doubt the user wants to install Cauldron on it, so please close it if you think it is resolved.

Closing as old is a way to resolve a bug, but it doesn't mean it'll be fixed in Mageia 2 stable

We don't have a Mga2a3 liveCD at the moment, but if you happen to have the Mga2a2 one, could you test without installing, then?

Comment 6 Marja Van Waes 2012-02-16 17:49:40 CET

Closing as OLD because there is nothing that can be done, now.

Please reopen if the issue is still present with Mga2b1 LiveCD, or later with Mga2 stable
