last kernel that boots for me is 2.6.31-5 24

[larry]

Since the upgrade to 2.6.31-6.25 and above, my laptop hp 6530b stopped to boot.
It goes to "waiting for root file system" and exits in the shell.

Some details: I'm booting from external USB disk enclosure not from the internal laptop drive !!
whilst on the emergency shell I tried to remove/insert the usb_storage module but this does not help. The module is removed/ inserted cleanly but no scan occurs so no new disks found.

I tried to bisect the problem but I encountered that git bisect and debian build system does not go well with each other.
More strangely the tag Ubuntu-2.6.31-5.24 is missing from the freshly cloned karmic kernel repo.

P.S the help message below this very frame is quite misleading !!
 "ubuntu-bug -p linux" leads to error message.

[This is an automated message. Apologies if it has reached you inappropriately.]

This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue.

If this bug really is a bug in the linux-meta package you can move it back to linux-meta and set the Status to Confirmed, or contact us on the #ubuntu-kernel channel on the FreeNode IRC server. Thanks.
