Comment 4 for bug 6550

It is an ext3 partition. Ext3 is just ext2 with a journaling layer bolted on top so when booting it is mounted as ext2 as you dont need the journaling features to read a kernel image.

As stated in the original bug report - I have installed dapper many times on 4 different hard disks (both using automatic partitioning and my own layout) but the kernel is still not uncompressed. Besides, If grub cannot find the kernel to boot it throws an error but as you can see in my pic, there is no error at all.
