Hi Thorsten,

Thanks for the update.  I'll attempt to find out if I can force a detach
on the host-side to recreate the issue on x86 while I'm waiting for a Z
system with FCP devices.

Could you attempt to use the Debian package from Sid on top of the
Ubuntu system?  This will help rule out kernel related issues vs.
userspace package bugs.

You can download from here

http://ftp.us.debian.org/debian/pool/main/m/multipath-tools/multipath-
tools_0.5.0+git1.656f8865-4_s390x.deb

And then force install with

sudo dpkg --force all --install multipath-
tools_0.5.0+git1.656f8865-4_s390x.deb

If this is successful, then I can prepare a package with some updated
fixes from upstream; there are a number of changes to path related
discovery in upstream multipath that aren't yet included in the Ubuntu
version.
