I think my case is different.

In my case, I used the startup disk creator on a working (and 
fully-updated) 15.04 system, so there should not be an incompatibility 
with the bootloader.

It was an UbuntuGnome 15.04 system I built the USB drive on.  Would 
there be an incompatibility between the bootloader on UbuntuGnome 15.04, 
as opposed to Xubuntu 15.04?

The USB drive created this way did boot successfully on a machine, and I 
was able to install (and test) software in the persistent storage.

But when I booted that USB drive (successfully) on another machine, and 
actually installed a Xubuntu 15.04 system to that machine's hard-drive, 
after (successfully) doing so, the next time I tried to boot the USB 
drive, it got the kernel panic error I reported before.

There appears to be something done during system installation (and 
manual partitioning) of the target machine's hard-drive that corrupts 
the USB drive containing the installation media.  There was no such 
problem when I had no persistent storage space on the USB drive (I only 
tried this once).
