All 3 logs contain (XEN) TSC_DEADLINE disabled due to Errata; please update microcode to version 0x52 (or later) Please load up-to-date microcode on the system and, preferably with Andrew's suggestions also applied, re-post the logs. I notice that even logs 1 and 2 have "Brought up 4 CPUs", other than you've indicated in your initial report. This suggests something's broken _after_ bringup of secondary CPUs, not while bringing them up. Log 3 effectively seems to confirm this. Seeing that "max_cstate=1" did help, as another next step could you try whether "mwait-idle=0" makes enough of a difference (it'll likely make a difference initially, as it makes the system effectively stay in a "max_cstate=1"-like mode until Dom0 has booted up far enough; the question this is going to be whether a hang still occurs one Dom0 has uploaded C-state data)?
