I'm getting some kernel panics running vgcreate, pvscan, vgscan on a
raid5 partition on a Compaq-DS10 , it sais free list corrupted ??
Any idea's , im kind of giving up on running lvm on this machine soon,
and it would really need it.
I could do a pvcreate -v /dev/md0 ( after dd </dev/zero >/dev/md0 bs=512
count= 1024 ), but a vgscan failed ( kernel panic, free list corrupted. )
and so did a vgcreate.
Any ideas ??
( at a point it complained that /etc/lvmtab and /etc/lvmtab.d was missing
I did a touch on those and it seemed to work ).
I find all this strange as I am running lvm on my laptop with no troubles,
but this installation is starting to hurt, ( ckraid on 72 Gig ).
/ best regards, Lars Segerlund.

This looks like a known problem with the old md code once reported
by Steve Brueggeman:

Please refer to: http://linux.msede.com/lvm/mlist/archive/0059.html
As suggested, please try to remove /dev/md[4-9] and /dev/md1[0-5]
and try if vgscan still results in a panic.
Hope this helps
