      Hello,

      if you can update OpenSUSE 12.1 there default package crash if you
      try to start, I'll be very happy. :-)

      
      Is there a multipath-tools version that I can download it with
      git?

      
      Regards,

      Roberto.

        Hello,

        I've compiled and installed on January on Opensuse 11.4 x64 from
        git://git.kernel.org/pub/scm/linux/storage/multipath/hare/multipath-tools.git


        the multipath-tools but previous 14 of May the module hang as
        described below.

        Now I've got 

        git-clone -b sles11-sp2
        git://git.kernel.org/pub/scm/linux/storage/multipath/hare/multipath-tools.git


        .

        and reinstalled, but I'd like to know if this problem was
        already resolved.

        
        Regards,

        Roberto.
