[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

[Sergio Callegari]

Ok, I think I am probably running into bug Bug #802626  or Bug #818177

What happens is that if I add --noudevsync to the lvm2 udev rule in
lib/udev and then I update the initramfs the delay disappears.

Thus adding lvm2 and udev to the bug.

However, I still wonder why I am running into this.

1) My other machines that are on LVM do not have this issue
2) It is completely unclear to me what changed in the -14 kernel so that this kernel shows the issue and -13 does not
3) My situation is not exactly the one in VG #802626 because my root filesystem _is_ on a logical volume

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:
  Confirmed
Status in “lvm2” package in Ubuntu:
  New
Status in “udev” package in Ubuntu:
  New

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.
