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 7.0 / 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 [email protected] with the following three commands included in
the
mail:
reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks
Cheers,
Moritz
