Version: 3.2.21-3
Hi,
i tried to get https://github.com/asb/spindle running,
but in ./wheezy-stage0 mkfs hangs forever.
kill -9 doesn't work on mkfs and qemu-nbd, and i can't attach with
strace (at least i can kill strace).
I guess qemu-nbd shouldn't segfault in the first place,
but the kernel should handle this better.
qemu-nbd -d (disconnect) doesn't work (and can't be killed either).

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
