I fear that the information that would be useful is no longer available
since you rebooted. The only way to figure this out would be to attempt
the upgrade and not reboot before debugging it.

Could you give as exact as possible directions on how somebody might go
about reproducing your upgrade scenario, including a complete summary of
your partitioning setup and exactly how you performed the upgrade?
