Comment 2 for bug 577120

I also have this problem on my new Asrock ION 330 Pro PC running Ubuntu 10.04. This is a diskless machine, and when I boot it from a USB stick, or external USB disk, grub2 is extremely slow. Loading a 3.9MB kernel takes 30 seconds from a USB stick, and loading a 7.4MB initrd takes 55 seconds. With an external 1TB USB disk, I get roughly the same figures. As a test, I installed grub1 on another partition on the same stick, and loading the same files with grub1 only takes a couple of seconds. That is about 10 times faster. The problem seems to be related to the hardware or BIOS, because I cannot reproduce this problem in a Dell Optiplex. The Asrock has an AMI BIOS.
