Partition manager crash while installing 10.04

[DFishburn]

I have two ATVs which I am attempting to setup at the same time.

I am also using the same software, but each have different USB keys
for the booting process to be used after I am finished. They both use
the same Mythbuntu 10.04 LTS USB key though.

Anyway, as I move through the install screens (which seem unbelievably
slow compared to the other ATV, BTW) I eventually get to the point
where I setup the manual partitions. As I move through this part of
the install (which is glacially slow) parted eventually crashes and I
submit an apport log.

I was hoping someone could eyeball what I have here and see if they
can find what might be wrong. I am figuring it has to do with my
setup of the partitions on /dev/sda.

So, I have reduced the Media partition on the ATV (40 GB) to 18 MB and
am creating a 20 MB ext3 partition to be used my Mythbuntu on the ATV
disk directly.

If I am missing output that would be useful, please let me know.

When I reach the install when I setup the manual partitions, this is
the chart I am presented with.


/dev/sda Type Size Used
free space 0 MB 0 MB
sda1 efi 35 MB 35 MB
sda2 hfs+ 419 MB 218 MB
sda3 hfs+ 943 MB 484 MB
sda4 hfs+ 17075 MB 25 MB
sda5 ext3 20996 MB 510 MB
sda6 536 MB unknown

/dev/sdc Type Size Used
free space 0 MB 0 MB
sdc1 hfs+ 24 MB 12 MB
sdc2 ext3 475 MB 222 MB


Some of these numbers look strange to me. For /dev/sda4 why would any
be used, when I shrunk it?
For /dev/sda5, when I setup the ext3 partition, which I thought would
clear this out.

mkfs.hfsplus -J -v Media /dev/sda4
mkfs.ext3 -b 4096 -L Linux /dev/sda5


Anyway, does anyone see anything wrong with the above?

If so, could you also give me some instructions on how to fix it.
Certainly my Linux skills are not high. Takes me ions to figure out
command lines.

Thanks,
Dave
