[3.0.0-14] Boot process hangs for 60 seconds on every boot

3.0.0-14 has introduced something that causes the boot-process to hang for 60 seconds (as seen in dmesg) on every boot.

Rolling-back to 3.0.0-12/13 and the problem disappears. However, the problems remains in 3.0.0-15 (Ubuntu proposed).

Issue is evident in dmesg between the lines:
[ 2.127796] EXT4-fs (dm-0): mounted filesystem with ordered data mode. Opts: (null)
[ 62.340192] init: ureadahead main process (306) terminated with status 5

Hardware is Lenovo X100e with Intel 320 SSD, and the software is a fresh install of Xubuntu (AMD64) 11.10 (LVM on GPT) and using flgrx driver (though also tested without).

I've had a look, and 3.0.0-14 includes a few EXT4 related patches, but I don't know if this is relevant to the problem?
