[linux-lvm] Follow-up: Help: lvm 0.9.1_beta3 oops (can't get my data)



More info:

If I don't touch volume group w0 (the one that has all my data), I get no oopses or SegFaults.  I was able to do the following after a fresh reboot into 2.4.0:

[root btexi0c1 /root]# vgscan

vgscan -- found inactive volume group "w0"

vgscan -- WARNING: This program does not do a VGDA backup of your volume groups

[root btexi0c1 /root]# vgchange -a y w1
