Subject: LVM Checksum error when using persistent grants (#linux-next + stable/for-jens-3.8)

Hey Roger,

I am seeing this weird behavior when using #linux-next + stable/for-jens-3.8 tree.

Basically I can do 'pvscan' on xvd* disk and quite often I get checksum errors:

# pvscan /dev/xvdf
  PV /dev/xvdf2   VG VolGroup00        lvm2 [18.88 GiB / 0    free]
  PV /dev/dm-14   VG vg_x86_64-pvhvm   lvm2 [4.00 GiB / 68.00 MiB free]
  PV /dev/dm-12   VG vg_i386-pvhvm     lvm2 [4.00 GiB / 68.00 MiB free]
  PV /dev/dm-11   VG vg_i386           lvm2 [4.00 GiB / 68.00 MiB free]
  PV /dev/sda     VG guests            lvm2 [931.51 GiB / 220.51 GiB free]
  Total: 5 [962.38 GiB] / in use: 5 [962.38 GiB] / in no VG: 0 [0   ]
# pvscan /dev/xvdf
  /dev/xvdf2: Checksum error
  Couldn't read volume group metadata.
  /dev/xvdf2: Checksum error
  Couldn't read volume group metadata.
  PV /dev/dm-14   VG vg_x86_64-pvhvm   lvm2 [4.00 GiB / 68.00 MiB free]
  PV /dev/dm-12   VG vg_i386-pvhvm     lvm2 [4.00 GiB / 68.00 MiB free]
  PV /dev/dm-11   VG vg_i386           lvm2 [4.00 GiB / 68.00 MiB free]
  PV /dev/sda     VG guests            lvm2 [931.51 GiB / 220.51 GiB free]
  Total: 4 [943.50 GiB] / in use: 4 [943.50 GiB] / in no VG: 0 [0   ]

This is with a i386 dom0, 64-bit Xen 4.1.3 hypervisor, and with either
64-bit or 32-bit PV or PVHVM guest.

Have you seen something like this?

Note, the other LV disks are over iSCSI and are working fine.
