Comment 2 Jesse Brandeburg 2013-01-16 07:10:15 UTC 
this bug was because my /etc/fstab was mounting ext3 filesystems as ext4.  I had done this because I upgraded to an SSD and wanted FS trim support.

I switched to F2 console and upgraded both partitions to ext4 with tune2fs command: tune2fs -O extents,uninit_bg,dir_index /dev/sdXy

I rebooted and install is proceeding.
Comment 3 Jesse Brandeburg 2013-01-16 07:32:00 UTC 
the upgrade finished, but the bootloader was not updated with the new kernel, so the old kernel booted the new system successfully. I think that is an already known bug.

I hope this bug report on F17 install is useful in fixing/preventing a bug in future upgrades, esp for users with long lived systems.
Comment 4 Chris Lumens 2013-01-23 15:29:08 UTC 
You should definitely not be seeing this problem with upgrades to F18, given that we are using a completely new upgrade process that uses system tools instead of anaconda, and those tools should understand your /etc/fstab better.  Thanks for the report.
