[Bug 235305] [NEW] kernel 2.6.24-17: boot hangs with "waiting for root file system"

[Tony Green]

Public bug reported:

Binary package hint: linux-image

Running Kubuntu 8.04.

After installing today's updates, I cannot boot my system with the newly
installed kernel (2.6.24-17) which hangs with a message "waiting for
root file system".

I can see that previous bugs have been raised for this problem in other
kernel versions, but as this is a new version I am opening a new bug.

Some of the previous bugs give the impression that this might have been
related to multi-core processors, but I only have a single core. (Not
sure why I've got an SMP kernel, as I thought this was meant for multi-
core CPUs.)

When the boot finally gives up trying to mount the root file system, it
drops into a limited shell. Looking in /dev in this shell, I can see no
/dev/hd? , /dev/sd? or even /dev/disk, which seems to explain why no
device can be found to mount.

As I can't mount anything to write logs to, I can only supply a limited
amount of what's been requested in previous instances of this, viz:

uname -a
Linux (none) 2.6.24-17-generic #1 SMP Thu May 1 UTC 2008 X86_64 unknown

cat /proc/version_signature
Signature Ubuntu 2.6.24-17.31-generic.

I have attached output from lspci -vvn, run from the previous kernel.

I am able to work around this problem, as I can still boot from the old
kernel.
