I experience the same issue, but for me it doesn't happen on every boot, only occasionally. I'm attaching my /var/log/boot.log which claims there are several problems, both with the swap disk (which seems to work fine) and with a disk that is a RAID array (which is present when I get to a desktop, unlike boot.log claims). But it doesn't seems to be associated with any particular partition. Except for my root and home partition, this seems to happen to a different disk each time it occurs.
