Bug#597828: linux-image-2.6.32-5-amd64: [xen] debug options + sysrq-t => sending NMI to all CPUs: BUG: unable to handle kernel paging request



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:
