Unfortunately I have not been able to test it yet. It looks ok to me except for patch 08 for which I still think something needs to be fixed. You can add on all the other patches: Reviewed-by: Aurelien Jarno <aurelien@xxxxxxxxxxx> Thanks, Aurelien -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurelien@xxxxxxxxxxx http://www.aurel32.net
