    Boot hangs for 60 seconds under 3.0.0-14-generic

    Recently installed Xubuntu on Lenovo X100e. After upgrade to kernel 3.0.0-14 the boot-process pauses for 60 seconds (where it did not under previous kernel).

    dmesg from 3.0.0-14-generic

    It appears to hang between EXT4-fs and ureadahead. This happens every boot under 3.0.0-14, but not when switching back to previous kernel.

    Details: Xubuntu 11.10 (LVM and GPT) on a Lenovo x100e with Intel 320 SSD.

    I don't know how to solve this, and I don't even know which logs to look in to find more information!

    Re: Boot hangs for 60 seconds under 3.0.0-14-generic

    I've noticed the same thing for a while now. Posting a recent dmesg log file which shows that udevd appears to take 60+ seconds to boot, during which time the machine appears to be locked with no HD or system activity.

    Should probably also mention I've got LVM file system spanning a couple of drives for fun and excitement.

    Code:

    Edit:
    Appears mine is a confirmed bug with udev and lvm2.
