Yes.
I looked at this problem using my shiny new BDI3000.
mpcl8572>select 0
Target CPU : MPC8572 Core#0
Core state : halted
Debug entry cause : COP halt
Current PC : 0xc000aae4
Current CR : 0x44044022
Current MSR : 0x00021000
Current LR : 0xc000aabc
Current CCSRBAR : 0x0_ffe00000

Target CPU : MPC8572 Core#1
Core state : halted
Debug entry cause : COP halt
Current PC : 0xc006db38
Current CR : 0x22000022
Current MSR : 0x00021000
Current LR : 0xc006ed10
Current CCSRBAR : 0x0_ffe00000
System.map:
c000a794 T __ipipe_send_ipi
c000a968 T ipipe_critical_enter
c000ab50 T __ipipe_enable_pipeline
c006da60 T ipipe_release_tickdev
c006daf8 T __ipipe_check_percpu_access
c006dbf4 T __ipipe_set_irq_pending
So, were stuck in ipipe_critical_enter() and __ipipe_check_percpu_access().
I'll try and pull this apart some more...
