Package: linux-2.6
Version: 2.6.32-23
Severity: minor

[ Note that this bug is against a kernel that has been modified to add
debugging options. I report it to debian only because I was suggested
so on #debian-kernel.]

Steps to reproduce:
1) To debug #580889 I rebuilt the kernel with various debug options:

$ diff -u /boot/config-2.6.32-5-amd64 /boot/config-2.6.32-5+lindi.1-amd64 |grep -v "#"

2) I then booted the kernel and used "xm sysrq lindi1 t" to get a
backtrace from all threads but forgot to run "xm console lindi1". (The
bug does not occur if you are connected to the console!).

Expected results:
2) domU does not crash

Actual results:
2) domU prints a lot of backtraces and then panics.

More info:
1) I was able to capture the panic message by running

sudo gdbserver-xen 127.0.0.1:9999 --attach 4
sudo gdb /local/lindi/vmlinux-2.6.32-5-amd64
dump memory dump.txt __log_buf (__log_buf + 4096*100)

on dom0:

Message-id: <20130708174005.GA7214@pisco.westfalen.local>
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 control@bugs.debian.org with the following three commands included in the
mail:

reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks

Cheers,
        Moritz
