Thanks. It is perhaps the jiffies calibration taking a while because of the precise timing loop. Are you reasonably confident that it is a regression in performance over 2.6.17? The boot sequence is pretty complicated, and a lot of it is difficult / slow to virtualize, so it could just be alternate timing makes the boot output appear to stall, when in fact the raw time is still about the same. I will run some experiments.
