I have been methodically going through my system converting each filesystem to 
reiserfs.  This entails the following sort of sequence for /dev/vg/foo

lvcreate -L <size> -n newfoo vg
mkreiserfs /dev/vg/newfoo
mount /dev/vg/newfoo /mnt
rsync -aHxq /where foo mounted/ /mnt
umount /mnt
umount /where foo mounted
edit fstab to change filesystem type to reiserfs
lvremove /dev/vg/roo
lvrename vg newroo roo
mount /where foo mounted

After a while (varies, but could be when I start to reuse the PEs? ) the 
initial lvcreate seems to get to a stage where it segfaults repeatedly until 
I deactivate and reactivate the vg (vgchange -a n vg ; vgchange -a y vg).

I have done this on my (only) two systems at home (each with two vg and 
between 2 and 5 lv on each vg).  One is running sid, the other sarge.

Looks like the kernel doesn't have recent patches and that the
devfs entry isn't updated properly on lvrename.
Marcelo has those patches and they hopefully show up in 2.4.21 so that there's
no need to patch the kernel any longer.

Make sure that the kernel gets patched following README/INSTALL instructions
contained in the 1.0.7 source tarball.
