LVM problems with disk on firewire card

Hey everyone, long time lurker making first post here.

I am having a weird problem I am hoping you can help with. I have a firewire controller installed in a Toshiba pc I bought some years ago and I have used LVM to create a couple of VG's.

I have connected a bytecc enclosure with a 200 GB hard drive to it and I have created a new PV for my VG and everything is ok. I extended my LV to include the new drive and everything was happy. Upon rebooting though LVM could not initialize the VG because it could not locate the PV anymore. When I go look at the partitions, I don't see my LVM partition on my disk anymore.

If I go through the process again (Setting up the drive to work with my VG) it all works, except for after rebooting where the same problem occurs again.

Here are some details and error messages:

dmesg output when I connect the drive to my system:ieee1394: Node changed: 0-01:1023 -> 0-00:1023
ieee1394: Node suspended: ID:BUS[0-00:1023] GUID[0050770e4000130d]

Disk /dev/sda doesn't contain a valid partition table

Unfortunately I don't have the exact messages for LVM since I reduced the LV so that I can access the other files on it. Basically, it would complain that it could not find device with uuid "blah blah blah" and would thus not activate the vg.

One time, I got an error that the controller was removed and then I ran kudzu and the next time if found the partition again and it worked ok.

I am curious if anyone has had success running LVM this way with an external firewire controller and if you have any tips for me.

So this is what I have narrowed it down to: each time I reboot either my partition is erased or something is causing Linux to not see the LVM partition.

I restored my cfg back to one that indluded the "missing" drive and did a pvcreate to restore it to UUID (needed -ff option). With the drive now back in the VG, I rebooted and the same thing happened again! No partition listed by fdisk -l. Please, please, any ideas?
