The 'Duplicate free' can be caused by a race between swapout_procs()
and kern_exit()+wait1().
The enclosed patch might help.
Disabling swapping (sysctl vm.swap_enabled=0) can also help.

problem on my -current machine today, I found that

I haven't been able to get a working SMP kernel out of -CURRENT recently.
I don't know exactly when it broke, because I usually rebuild on a weekly
basis. The kernel hangs after:
APIC_IO: Testing 8254 interrupt delivery
and doesn't ever come back (panic or otherwise).
The one thing that I
might be a workaround for this second problem (causing
the memory below 16 MB not already allocated by vm_page_startup to be
in the middle of the page queues).

Actually, it broke fsck_ffs.
Workaround to avoid the known broken case:
The brokenness in ix86_expand_clrstr is quite visible when you
compare the function with ix86_expand_movstr.

I had the same problem. Changing the sio code to require three breaks
inside a 10 seconds interval before dropping into the debugger reduced
the problem for me.
