Installer crashing at disk-partition stage

[Edward Speyer]

I'm finding the Breezy installer is crashing at the disk-partitioning
stage.

This is what the syslog looks like just before the installer restarts:

At first, I thought I might have a corrupted install CD.  The md5sum is
indeed wrong when I checked it on this laptop.

So I burned a new, net-install only CD.  I think a net-install downloads
the udebs for disk partitioning from the ubuntu mirror.  (Thereby
avoiding having to get this software from a corrupt CD.)  However, the
installer still crashes at the disk-partitioning stage.

For what it's worth, as the bootloader help screens suggest, I've tried
booting with the "nolapic" and "noapic" kernel options, though I don't
really know what they do.

Any tips?  I guess finding out what's actually broken would be a good
start :)
