Bug#613634: linux-image-2.6.32-5-xen-amd64: Using pvcreate on a multipathed iscsi device produces a kernel bug
 
Package: linux-2.6
Version: 2.6.32-30
Severity: grave
Justification: renders package unusable

I'm using a Dell powervault MD3200i that has 2 iscsi controllers with 4 ethernet ports each. The multipath-tools package is used to aggregate all links in a single device (configuration is attached).
All of this is used on a Xen host with 4 network controllers : eth2 and eth3 are dedicated to the iscsi network, and eth0 and eth1 are bonded and used in the xen bridge.
Creating file systems and using them seem to be working perfectly after very basics tests (mkfs.ext3, copy / read files). However, if I want to create a volume group on such a device, everything goes west :
