The following error occurred in a manual partitioning test of amd64+mac image of 20130923.2 on Mac mini 5.1
"Error informing the kernel about modifications to partition /dev/sda2 -Device or resource busy. This means Linux wont know about changes you made to /dev/sda2 until you reboot- so you shouldn't mount it or use it any way before rebooting."
The following is seen in dmesg

===================================
Steps:
1. Start the installation
2. Go straight to 'Install Ubuntu' ( since live session installation is broken at them moment)
3. Select 'something else' in the Installation type menu to perform manual partitioning
4. Select Ext4 file system for /, /boot and /home partitions leaving adequate swap space
5. Click continue and the above errors will be reported
