Hi, I got the same Problem on a freshly installed Debian 5-box.

I've found the same bugreport for gentoo: http://bugs.gentoo.org/show_bug.cgi?id=232630 they mentioned, it may be some kind of timing issue, but there is no fix for it. I installed some other boxes from the same repository (also Debian 5) and there is no such behaviour. kind regards jm kind regards jm -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
