FYI - check that this patch (included in device-mapper 1.02.49)
Fix semctl parameter (union) to avoid misaligned parameter on some arches.
http://sourceware.org/cgi-bin/cvsweb.cgi/LVM2/libdm/libdm-common.c.diff?cvsroot=lvm2&r1=1.69&r2=1.70
(and possible others) is included (I see on Debian unstable still use 1.02.48).
If not, please report bug to Debian. It is not easy to convince Debian lvm/dm
maintainer to do an update there, though:-)
