I created a perf timechart (attached) to see if that would illuminate the problem. This is taken from the installer environment for the first 30s.

In this boot, the soft lockup occurred on CPU 11:
  [ 32.815351] NMI watchdog: BUG: soft lockup - CPU#11 stuck for 22s! [swapper/11:0]

This blocked period appears to be visible from the chart, but it isn't clear to me what it was executing at the time.
