Yes, as mentioned in #6, adding the --noudevsync parameter fixes the
delay for me.
Now, I wonder if it is just me, or also others have the same experience.
IMHO, this is important to know because the bug title in 802626 is about
those who have the root filesystem outside LVM and all the rest in LVM,
i.e. a rather restrictive case, but the proposed fix (at least for me)
corrects the boot delay also in a more general cases (I have the root fs
in LVM).
If it fixes the bug for everybody, we can mark this bug as a duplicate
and widen the title of 802626.
In the meantime, note that while the --noudevsync fixes the delay, I do
not know if it may have nasty side effects on some configurations. I do
not have a good enough knowledge of udev, but for sure the man page of
lvm says that --noudevsync should be used with care.

Title:
Severe regression with latest kernel update: 3.0.0-14.23 takes an
unreasonable amount of time to boot due to udev
Status in “linux” package in Ubuntu:
Triaged
Status in “lvm2” package in Ubuntu:
Confirmed
Status in “udev” package in Ubuntu:
Confirmed
Bug description:
After the kernel update the machine takes ages to boot. At first I
thought that the machine was not booting at all, but in fact it is,
only taking an absurd amount of time where no disk activity is shown.
The boot appears to hang at /scripts/init-bottom.
The same symptom is present with the 3.2RC4 kernel on the mainline
ppa.
