Laszlo,
I may not state the problem very clearly.
I saw two problems:
1. ParitionDxe shouldn't create BLK handle for the entire media again. Our QA
complains
several new but unexpected BLK devices are seen. This bug is easy to fix
and needs to
be fixed ASAP. So I created a BZ
(https://bugzilla.tianocore.org/show_bug.cgi?id=707).
2. PartitionDxe should handle multiple LVDs in a UDF CDROM. No one complains
this.
I am fine to accept the limitation. So I even didn't create a BZ.
Anyone who wants this support can submit a BZ.
I guess following the same pattern of existing code to support it should
be easy.
Thanks,
Ray

Ray,
from the discussion it looks like the issue only hits with multi-volume media.
Paulo stated he had never seen such media. Can you share your reproducer media
perhaps (even privately, if it can be done legally), or else provide
instructions to create, or obtain, such media?
Thanks!
Laszlo
