[Bug 902491] Re: Severe regression with latest kernel update: 3.0.0-14.23 takes an unreasonable amount of time to boot due to udev

I've also run into this bug.

3.0.0-14 introduced a - precisely - 60 second delay into my boot-time.
Tried 3.0.0-15 from proposed, with the same result. The only way to
alleviate it was to roll-back to 3.0.0-13 (last kernel to not exhibit
this behaviour). I've also tried a 3.2 kernel from Pangolin, and this
too displays the delay.

I have my entire root file-system on LVM Including /boot), on GTP on an
SSD.

I've now tried the "--noudevsync" fix and can confirm it removes the
60-second boot-delay when running 3.0.0-14 (and presumably all later
kernels).

I'm interested in comment #2, which notes that this issue may be t
related to:

# Stop udevd, we'll miss a few events while we run init, but we catch up
udevadm control --timeout=61 --exit

...as this duration exactly matches the delay I experience.

I had registered a bug about this (909805), but I've now marked it as a
duplicate of this bug.

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.
