dmesg output (Full Log)
There are two noticable jumps (4Seconds+) so these are below:

.....

So that's the output, giving me a few questions,

  1. How do you read the log?
    • [ 38.443264] init: plymouth-stop pre-start process (3524) terminated with status 1
      [ 57.933258] audit_printk_skb: 39 callbacks suppressed

      There is a gap of 19.489994 so is that gap while init: plymouth-stop is running, or while audit_printk_skb is running?
  2. What can I do to further debug this?
  3. What can I do to solve this?

Note: ..... in the dmesg just means I removed a section of the log there. –  Hailwood Nov 2 '12 at 1:34
