The issue still remains. Since the initial report was done using a live USB session, I did an install on a spare hard drive so I could try the latest mainline kernel, RC6, but the error still remains. In addition to sudo hanging when this issue is present, shutdown also fails. With the wifi card removed things work as expected.
