I am running Ubuntu 10.04 as well and have been using ext4 exclusively
for a couple of years now on multiple machines.  At first, I had lots
of corruption problems like you experienced.  (This was very common when
ext4 first came into mainstream use [1].)

I solved all my ext4 reliability problems by adding the following mount
options to each ext4 filesystem in my fstab:

    journal_checksum,nodelalloc,auto_da_alloc

Colin
