panic: ipi_send: couldn't send ipi

[Kris Kennaway]

I got this on a dual ultra 60 running -CURRENT that I'm using for
package builds:

panic: ipi_send: couldn't send ipi
cpuid = 0;
Debugger("panic")
Stopped at      Debugger+0x1c:  ta              %xcc, 1
db> trace
panic() at panic+0x170
cpu_ipi_send() at cpu_ipi_send+0xb8
cpu_ipi_selected() at cpu_ipi_selected+0x38
tlb_page_demap() at tlb_page_demap+0x158
vm_page_zero_idle() at vm_page_zero_idle+0x78
vm_pagezero() at vm_pagezero+0xc0
fork_exit() at fork_exit+0x9c
fork_trampoline() at fork_trampoline+0x8
db> call dumpsys
panic: trap: fast data access mmu miss
cpuid = 0;
Debugger("panic")

Any ideas?
