Hmm.  The bad log has

  [    7.015708] usbcore: registered new interface driver uas
  [   25.552030] random: crng init done

In the good log, there are several other messages in between:

The other thing I noticed when comparing the logs is that the initial
USB-related messages are different, like the devices are being
recognized in a different order.  I don't know if that's significant or
not.

I'm afraid I didn't record the exact messages that I got during my
original attempts to install.

With the live image failures that I'm getting now, the console messages
are

  [   30.010394] usb 1-1.2: reset high-speed USB device number 3 using ehci-pci
