Trouble booting new drive (1 reply)

I'm attempting to upgrade the HDD I have attached to my pogoplug v4 mobile from a 1TB to a 4TB. To support a single partition greater than 2TB, I'm using a GPT partition table rather than an msdos partition table. I'm using GParted 0.33.0 to do so. When I attempt to boot the drive, I see the following in netconsole:

If I switch to creating a smaller partition on the same disk using msdos partition table, I can boot just fine. What am I doing wrong? Is gparted creating this hybrid partition table I keep reading about, even though I select "gpt"?
