--- Begin Message ---Hi, your bug has been filed against the "linux-2.6" source package and was filed for a kernel older than the recently released Debian 7.x / Wheezy with a severity less than important. We don't have the ressources to reproduce the complete backlog of all older kernel bugs, so we're closing this bug for now. If you can reproduce the bug with Debian Wheezy or a more recent kernel from testing or unstable, please reopen the bug by sending a mail to cont...@bugs.debian.org with the following three commands included in the mail: reopen BUGNUMBER reassign BUGNUMBER src:linux thanks Cheers, Moritz
