dtrace script matching lot of probes simply resets on i386

Hi,

I had an i386 kernel (amd64 machine) simply going to POST.  After a lot 
of “doh” I realised that it was a dtrace script which was matching a 
lot of probes running as part of some automated stuff.

The problematic part from the middle of that script was a section which 
I can reduce to

fbt:kernel::entry		# or simply :::
/self->foo == 1/
{

    printf(“Hello\n”);
}

Anyone wants to investigate this or should I open a PR?
