Subject says it all, brand new install on a brand new SSD, crashed. Manual partitioning might have something to do with it.

UpgradeStatus: No upgrade log present (probably fresh install)
Hard power off and a second install keeping only to the defaults worked. What I was trying to do the first time was add more swap that was there by default. I guess if I really want to do that now I can fiddle with it in LVM.
So I probably goofed something up when manually partitioning, but the error message was totally worthless: install crashed or something similar... I didn't notice any indication of where to do looking for logs, and though perhaps I could have found some logs it was easier to just start over.
Also note, if it matters, that the machine is a circa 2009 Dell mini9 (Atom), hence the need for 32-bit.
