Ubuntu install hangs on partitioning @43%

Many sites are recommending setting up the partition table on an SSD using:

• fdisk -H 32 -S 32 /dev/sdx

Unfortunately for a complex partitioning scheme this causes Ubuntu partman to hang during installation (at 43% in my case).

I discovered that:

• fdisk -H 224 -S 56 /dev/sdx

Works just fine.
