I have solved the problem for now, but live in fear that there is something untoward going in on my hardware. Earlier on, this was intermittent. I also wonder whether a register was set or a cmos flag, because after I booted the Ubuntu partition, the machine did boot with no complaint. It hadn't been going on long, though. Well, I finally was able to boot using an earlier kernel with no MCE flag set, then recompile a newer kernel without it. I think your solution is the better one, though. I did follow the instructions of the boot messages and installed an mce log translation utility, but I didn't make sense of what to do with it.
