Thread: Hang early in boot with 2.6.27-git

  1. Hang early in boot with 2.6.27-git

    Latest git (head 2515ddc6db8eb49a79f0fe5e67ff09ac7c81eab4) hangs early
    in boot. One clue is that if I let it sit there for ~30 minutes, I get
    a message about the tsc being unstable... the last messages are:

    [ 2.255064] NET: Registered protocol family 2
    [ 1528.453016] Clocksource tsc unstable (delta = 1499794012204 ns)

    Any requests for debugging info or suggestions appreciated...

    System is a dual-socket quad-core Xeon box. Full boot log below:
