My understanding is that the 2.6.37 is being developed for Natty (http://kernel.ubuntu.com/~kernel-ppa...rsion-map.html) . Do we need to wait until next April to fix this issue?

I have been struggling with exactly the same problem on my AMD Athlon 64x2 Dual Core Processor. Spent almost all day trying to find a solution and even tried re-installing from 10.04, doing a distro update etc... just to get the same problem again. 10.10 disk does not work.
I tried to replace the UUID address with a simple /dev/sda1 , but got a further error: Target filesystem does not have requested /sbin/init. No init found.
I also downloaded the latest Natty installation disk, but it will also not boot - with the same error that I get from the 10.10 disk (Unable to find a medium containing a live file system).
I'm glad I found this thread, otherwise I was going to sleep very badly tonight
Hello
you can get 10.10 working on Dell T3500 by just adding
pci=nocrs
to your bootloader's kernel arguments.
2.6.37 will contain a code-fix which will make that work out-of-the-box, but I understand that this fix could be applied to older Linux kernels as well.
Another satisfied customer of the proposed pci=nocrs workaround! For those (like me) who aren't familiar with grub tampering, here's what I did to make the change automatic:
sudo cp /boot/grub/grub.cfg /boot/grub/grub.cfg.orig
sudo cp /etc/default/grub /etc/default/grub.orig
sudo vi /etc/default/grub
# < # GRUB_CMDLINE_LINUX=""
# < GRUB_CMDLINE_LINUX="pci=nocrs"
# ---
# > GRUB_CMDLINE_LINUX=""
sudo update-grub
The first two lines are optional, but I knew /boot/grub/grub.cfg was going to be modified, so I made a backup to make it easy to restore, in case I did something stupid. Same thing for /etc/default/grub, which I changed directly (using vi, but pick your favorite editor). Change the GRUB_CMDLINE_LINUX variable to include the pci=nocrs fix. Then run update_grub to incorporate the change. Reboot. Enjoy 10.10. -- jpl

Thanks for the tip folks -- it works great on my Dell T3500. The added bonus is that I can finally mount an external eSATA drive now that AHCI works.
Thank a million bmwiedemann!
I had a stressful day trying to solve this problem on my Dell Precision T3500, with no luck, until I found your suggestion.
I just rebooted with the pci=nocrs option and it worked.
Thanks again, good job!
Hi,
I have the same T3500 machine and am unable to install Ubuntu 10.10
How do I add pci=nocrs to bootloader's kernel arguments? I am unable to boot into the system itself. After the small human appears the system just reboots.
Thank you for your time.
A quick update. I upgraded to 11.04, and, with some trepidation, said to install the default grub loader when the install offered to preserve the loader with pci=nocrs. I'm pleased (but not really surprised) to say that the default loader works just fine with 11.04. It's nice to get rid of one more exception to the standard setup. -- jpl
