Bug#633880: mdadm: breaks booting with empty sublevel definition in uname -r (like kernel 3.0)

[Stefan Lippers-Hollmann]

Package: mdadm
Version: 3.1.4-1+8efb9d1
Severity: minor

Hi

Using a kernel with empty SUBLEVEL definition, like

VERSION = 3
PATCHLEVEL = 0
SUBLEVEL =
EXTRAVERSION = -rc7
NAME = Sneaky Weasel

breaks booting with / on LVM2 on RAID1 (mdadm), as the RAID array can't
be assembled. An according fix has been added to Fedora with

http://pkgs.fedoraproject.org/gitweb/?p=mdadm.git;a=blob;f=mdadm-3.2.1-version.patch;h=2a935e97ced2b244249496d3a758ae119aee548f;hb=HEAD
(I can confirm this patch to be working, if I ignore -Werror - #625392)

Be aware that current Debian kernels in experimental define SUBLEVEL 
as 0, to defer compatibility issues like this. So this won't be an
immediate issue in Debian, although it would be nice to get this fixed
to work with upcomming upstream kernels.
