ssm list shows -

/dev/lvm_pool/lvol001

When I place /dev/lvm_pool/lvol001 into /etc/fstab the computer will
boot using kernel 514.
Kernel 862 still hangs/panics.

I don't have an answer to why kernel 514 is not booting,
but what I was trying to say is:

/dev/lvm_pool/lvol001
and
/dev/mapper/lvm_pool-lvol001
are both symlinks to the same /dev/dm-X device file.
You can use either name, but the one you listed was missing the volume
group name

kernel 514 does boot.
kernel 862 hangs/panics.
I will try both entries in your example above on kernel 514 to confirm.
If both work then I'll try them also on kernel 862 to see if possibly
one will work.
thanks for your help.
