I had a first quick look at this, and it doesn't reproduce with udevadm trigger in the booted system, and not even with init=/bin/bash and starting udev/udevadm trigger manually.
** Description changed: Since the update to 2.6.32-11 from -10, usb_id hangs for 5 seconds. Compare - http://people.canonical.com/~pitti/bootcharts/daniel-lucid-20100122 - -unity-wncksynccache-noxrdb.png (2.6.32-10) + http://people.canonical.com/~pitti/bootcharts/daniel- + lucid-20100121-1.png (2.6.32-10) with - http://people.canonical.com/~pitti/bootcharts/daniel-lucid-20100121 - -unity-wncksynccache.png (2.6.32-11) + http://people.canonical.com/~pitti/bootcharts/daniel- + lucid-20100122-1.png (2.6.32-11) This is both on current lucid on the same machine (Dell Mini 10 SSD, reference platform for boot speed goal). I haven't investigated yet whether this is really a kernel regression or a previously hidden bug in usb_id/udev. ProblemType: Bug AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
