i maked the VG and the LV's under 2.4.9-xfs lvm-1.0.1rc1
but i had the XFS- mount problem with it and JFS had no problems
and i upgraded to 2.4.10-pre2-xfs lvm-1.0.1rc2 and had no problems with 
JFS and XFS
i tried with 2.4.9-ac5 lvm-1.0 and vanila 2.4.9 lvm-1.0.1rc1
with all these kernels it seemd that the LVM is working but i couldn't 
format the LV with reiserfs and ext2
mke2fs and mkreiserfs simply segfaults without errors

i can not understand why do you think that i could have RAM problems
if i had RAM problems why would XFS and JFS working without problem and
mke2fs and mkreiserfs segfaulting
