multipathd: 8:80 mark as failed - BUG: unable to handle kernel NULL pointer dereference at (null)

[-- Attachment #1.1: Type: text/plain, Size: 25521 bytes --]

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.
