Hi there,
I ran sudo apt-get upgrade today and I *think* one of the things it did was install a new kernel (8.04.1 kernel 2.6.24-19-generic). After rebooting, the root file system couldn't be detected anymore.
If I try to use the newest kernel, it waits for a long time at Waiting for root file system and then, it winds up with an initramfs prompt.
I then tried logging in recovery mode for the newest kernel, and got this instead:
Waiting for root file system...
Clocksource tsc unstable ...
Time: hpet clocksource has been installed
Gave up waiting for root device
...
ALERT! /dev/disk/by-uuid/... does not exist! Dropping to a shell!
and then I get the initramfs prompt.
I then thought I could get around this by going back to an older kernel (which has been working fine all the while). I then got:
Failed to start X server
Fatal server error
...
AddScreen/ScreenInit failed for driver 0
Eventually I managed to get a prompt using the recovery mode of an older kernel, but no X.
I googled for a few solutions including here at ubuntuforums, but none of them have changed anything so far. I've tried:
Adding rootdelay=90 to the kernel line. Didn't help - in any case, most people for whom this worked seemed to be able to get in eventually after letting the boot process take its time, which didn't happen for me.
Adding all_generic_ide to the kernel line. Again didn't help.
Running sudo update-initramfs when I managed to get a prompt. I got the message: cp: cannot stat '/lib/udeev/hotplug.function'. I think it did finish executing and this was just an error message. Nevertheless, nothing changed.
Cross-checking the UUID of / in the kernel line against what's in /etc/fstab. It's the same.
Upgrading to Intrepid Ibex. When I tried selecting manual partition so I could keep the partitions the same, again it failed telling me it couldn't find a root file partition. I stopped there as I didn't want to overwrite any existing partitions.
If anyone has any more suggestions I'll be happy to hear them. I'm running a Fujitsu Lifebook S Series if that's relevant. I can also provide more diagnostic material if you tell me where to find it. Thanks!!
