I used live upgrade to update a U6+lots'o'patches system to vanilla U8. I
ran across CR 6884728, which results in extraneous lines in vfstab
preventing successful boot. I logged in with maintainence mode and deleted
those lines, and the U8 BE came up ok. I wasn't sure if there were any
other problems from that, so I tried to activate and boot back into my
previous U6 BE. That now fails with this error:
***************************************************
* This device is not bootable! *
* It is either offlined or detached or faulted. *
* Please try to boot from a different device. *
***************************************************
NOTICE:

panic[cpu0]/thread=fffffffffbc283a0: vfs_mountroot: cannot mount root
I can still boot fine into the new U8 BE, but so far have found no way to
recover and boot into my previously existing U6 BE.
I booted both BE's in verbose mode, the working one:

Any idea what's going on? Why is the U6 BE trying to mount a disk partition
instead of the appropriate zfs filesystem? Here's the grub config if that
helps:
