Comment 15 for bug 245794

Hi Julian,

If you want to have another go with 9.04, before trying the installation,
remove 1 of the 2 Gb or RAM stick (I assume you have 2 nearly identical
sticks). After the installation, just put back the stick.
I know it sounds really weird, but it worked for me and some other Ubuntu
user, including the genius who have figure it out. The reason of this
problem seems to be related to some difference on the memory sticks. That
is, 2 identical sticks, but from different brands, must still have a small
difference, which trigger this nasty problem.
I leave to others, much more competent of me, to explain it and possibly
find the solution.

Here the page where I found the solution that worked for me:

Wish you good luck
:)

My system: AMD Athlon 64 X2 dual core 5000+, 4 GB ram, etc.. It was sold
with only 2 GB RAM, but I asked the system seller to install 2 extra GB)
