Hi
I try to install ubuntu natty daily build.
I had the partition corruption because 8Gb SD card...
After fsck, the installer starts.
At the end of the install process, the board reboots, and the
installer start again....
I don't know if it is a "normal" reboot.
For every issue before the first reboot, you may report them here: https://bugs.launchpad.net/ubuntu/+source/jasper
I have similar issue. I have tried to install beta1 and beta2 image to
Transcend class6 8GB sd card several times (like 3 times the beta1, 2
times beta 2) and had no luck. It went always like this:
- extracted image to card via zcat | dd
- booted in pandaboard
- first boot the screen on hdmi monitor said it is resizing image
- then it rebooted and showed some progress dots going indefinitely
- after waiting hour or more I powered off the board
There is no kernel console output either on serial console or any
virtual console (it can be switched via alt Fx keys) so I am not sure
there are I/O errors while it runs but it is very likely because after
trying beta 1 and removing it from pandaboard the card became corrupted
to the point that I could no longer rewrite the image via dd. Also
panasonic sd formatter failed repeatedly when formatting via full
format. After few hours of formatting it repeatedly it always failed at
some sector and card became dead, after reinserting card the format got
a bit further - the first bad sector was few megabytes later. After
several formats (5-10?) it healed itself and now works fine again. I
used this card quite a lot with linux filesystems before trying it in
pandaboard and it appeared to be good and had no issues with it before.
I had no time to investigate further. It would be nice if Natty beta
images had kernel console output or some sort or verbose output enabled
or at least had some debug version of boot.scr ready on the card for
those without u-boot utils ready. Also root shell on some console would
be nice when the install runs.
Some ideas about i/o errors:
Are SD card partitions (at least the second linux ext3 or ext4? one)
properly aligned to 1 or 4MB boundary ( before or after fs resize) as per
https://wiki.linaro.org/WorkingGroups/Kernel/Projects/FlashCardSurvey ?
If not then it could explain lot of i/o error issues with larger cards.
Would a larger ext3/ext4 filesystem block size (like 16/32/64KB instead
of 4KB) help with forcing the kernel to write in bigger blocks?

I seem to get
this more frequently when piping the decompressed images through dd
(i.e. zcat <image>.gz | dd of=<SD card device>). Could you try
gunzipping the image first, then using "dd if=<image> of=<SD card dev>
bs=4M" and see if you still have issues?
I will try again (hopefully today evening) and use cmp to compare the
card data back after writing the image (and reinserting the card reader)
and also check partition alignment both before and after resizing to see
whether this may be an issue.
gunzip natty-preinstalled-netbook-armel+omap4.img.gz
sudo dd if=natty-preinstalled-netbook-armel+omap4.img of=/dev/sdb bs=4M
This works fine.
I modify the wiki ?
Thanks.
David.

This is probably because the installer failed to recreate the initrd
with the proper content, that would avoid loading oem-config again at
the next reboot. As gunzip and then dd worked for you, it could be the
case that previous method failed to properly write the data at your SD
card.
