Kernel panic in "subr_xcall.c"

[Matthias Scheler <tron%zhadum.org.uk@localhost>]

        Hello,

a NetBSD/i386 kernel built from 2009-10-18 current sources crashes on my
four core virtual machine (VMware Fusion 2.0.6) here during system startup:

static uint64_t
xc_lowpri(u_int flags, xcfunc_t func, void *arg1, void *arg2,
          struct cpu_info *ci)
{
[...]
        KASSERT(xc_tailp < xc_headp);
[...]
}

A kernel built from 2009-10-16 sources works without problems.
Any ideas what could cause this?

        Kind regards
