When trying to boot to kernel 2.6.32-21 after upgrading from 9.10 to 10.4 I am unable to boot Ubuntu. It boots fine with kernel version 2.6.31-21. This occurs even when using the recovery option for kernel version 2.6.32-21. I do see errors about ext4 not being a recognized file system, even though it worked fine with 9.10 and with the 2.6.31-21 kernel. I would include log files but am not sure how to since I am completely unable to use the computer after the kernel version is selected in grub.

the new ubuntu 10.4 shifts to kernel modesetting
if your machine has intel graphics use
i915.modeset=1
as an option in grub boot menu

It uses an AMD graphics card, with no on-board video. Would this or a similar option help?

I was able to boot by adding radeon.modeset=1 to /etc/default/grub.
But one problem I am having is I get the message "press S to skip mounting, or M for manual recovery" shortly after grub starts booting Ubuntu. Is there a way to get rid of this? I have a couple of network drives mount at boot in fstab, sometimes they are booted, sometimes they are not. Either way I would prefer Ubuntu to complete booting without intervention.
I checked fstab, some of the mount points changed, and after correcting them, I no longer receive this message.

Hi! I got the same message, "press S to skip mounting, or M for manual recovery".
But my situation is a little different, I has been using a vanilla recompiled 2.6.33 kernel (without initrd) for months with 9.10 and with Beta 2, but when I installed some updates last tuesday everything broke up and since then I can no longer boot with that kernel, boot sequence stops after that message.
If I press M, then a root console appears and my data on root partition (that is correctly mounted... it seems strange as it claims that "/ cannot be mounted"!). But my home, that is encrypted and on another partition, is not there..
The system worked PERFECT just before I rebooted.
Everything is fine with Ubuntu kernel 2.6.32, also after I recompiled it (but with initrd this time). I did not tried using 2.6.32 without inirtd, maybe I will try this weekend.
I think that something is not working pretty well after that update.

add
,nobootwait
to the drive lines in fstab
eg.
defaults,...,nobootwait
and see if that helps
