Right.  Here's the output of running that vmpageinfo program.  

This is from the first core I posted the backtrace to in the original PR:

% cat vmpageinfo-25.out 
Script started on Mon Nov 15 14:22:37 2004
vm_page_buckets[262139] ((struct vm_page *)0xc0fddd40) page not found in bucket list
vm_page_buckets[262137] ((struct vm_page *)0xc0fe0248) page not found in bucket list
vm_page_buckets[262139] ((struct vm_page *)0xc1214e24) page not found in bucket list
vm_page_buckets[262137] ((struct vm_page *)0xc121d59c) page not found in bucket list
page 131042
kvm_read: Unknown error: 0

Script done on Mon Nov 15 14:25:21 2004

And this is from the core I generated at the weekend -- ie with the
vm_page.c patch applied:

% cat vmpageinfo-30.out
Script started on Mon Nov 15 14:26:05 2004
kvm_read: Unknown error: 0

Script done on Mon Nov 15 14:26:39 2004

At least, that's what's left displayed on the screen at the end.  If
you want the full output including all of the animated counters, it's at:

    http://www.infracaninophile.co.uk/vmpageinfo-25.out
    http://www.infracaninophile.co.uk/vmpageinfo-30.out

I'll try and get the INVARIANTS and INVARIANT_SUPPORT stuff into a
kernel ASAP -- but probably not before next weekend though.

	Cheers,

	Matthew
