OK, so I've tried. I did a boot of the Beta 1 image, and everything
seemed fine, so I rebooted into 14.10 and ran the upgrade. Boom.
Wouldn't boot. Not even with the old kernel, I just got a black screen
after GRUB. Trying to figure it out, I rebooted from the 15.04 Beta 1
image again and installed it, without checking the box to download
updates while installing. Booted fine. apt-get update && apt-get
dist-upgrade - no boot.

So now I have 14.10 reinstalled, thankfully that went fast, since I
have backups and a separate /home. I've downloaded the latest daily
image and written it to a USB stick, and intend to see if that will
boot later today. If it doesn't, then there has obviously been a recent
change that hangs on my machine. If it does boot, however, then I'm
utterly lost.

Is there anything anyone can suggest to track down exactly what hangs?
It must be really early in the boot process, because there are no
messages after I removed "quiet splash" from GRUB.

OK, thanks, I didn't know that. /home is on a separate disk, anyway.

Any tips on where I can start to debug this would be appreciated. I
already have an updated 15.04 VM that runs fine, so I'm suspecting a
hardware or kernel problem that I just haven't noticed in 14.10, though
that has been perfectly stable.
