lseek errors after pvcreate on RAID5

Hi,

I've made RAID5 on 4 disks in (unreleased) Debian GNU/Linux Etch, which
means linux-image-2.6.15-1-686 2.6.15-8, mdadm 1.12.0-1 and lvm2
2.01.04-5.  Here is the output of mdadm -D /dev/md1:

/dev/md1:
         Version : 00.90.03
   Creation Time : Fri May  5 17:26:32 2006
      Raid Level : raid5
      Array Size : 467394816 (445.74 GiB 478.61 GB)
     Device Size : 155798272 (148.58 GiB 159.54 GB)
    Raid Devices : 4
   Total Devices : 4
Preferred Minor : 1
     Persistence : Superblock is persistent

     Update Time : Fri May  5 20:45:07 2006
           State : clean

            UUID : 1f3449d3:840d444b:2a767e13:7f2f67b3
          Events : 0.102

     Number   Major   Minor   RaidDevice State
        0       3        2        0      active sync   /dev/hda2
        1       3       66        1      active sync   /dev/hdb2
        2      22        2        2      active sync   /dev/hdc2
        3      22       66        3      active sync   /dev/hdd2

The problem is that after pvcreate /dev/md1, pvs command shows the
following:

   /dev/hdd2: lseek 4611824548366092288 failed: Invalid argument
   /dev/hdd2: lseek 4611824548366092288 failed: Invalid argument

   /dev/md1        lvm2 --      445.74G    445.74G

Any idea what's happening?
