vkernel stuck in umtxsl state when booting from a NFS root mount

[Matthew Dillon]

:When booting a vkernel with '-n 1' I'm not sure when was the last time that it
:got stuck, while booting with '-n 2' fails in most if not all cases.

    It will take some time to reproduce this, I have to set up a
    NFS network root.
