System crash dump analysis report
=================================
Symptom
=======
  System panic with panic string : Illegal instruction trap

Root cause
==========
  Cpu 1 with HPA 0xfffffffffffa2000 didn't check in, and
  the IIR (CR19) from the savestate and the instruction pointed to
  by PCOQ are not consistent !
  IIR = 0xffffffff, PCOQ = 0x34240, *PCOQ = 0x8300400a

Action plan
===========
  Replace CPU 1 at path 162, hpahv fffffffffffa2000

Trap Types :

Trap type 8 = Illegal Instruction Trap (I_UNIMPL_INST)
Trap type 31 = Panic Trap (T_PANIC)

SPL/EIEM values:

0xfffffffeffffffff = SPLPREEMPTOK - Default user mode SPL level.
0xfffffff0ffffffff = SPLNOPREEMPT - Disable kernel preemption (scheduling interrupt off).
0xffffff00ffffffff = SPL2 - Disable software interrupt (software triggers off).
0xef00080000000000 = SPL5 - Disable IO modules.
0xc700000000000000 = SPL6+CLOCK_RESYNC - Disable hardclock+enable clock-resync.
0xc600000000000000 = SPL6 - Disable hardclock.
0x0000000700000000 = SPL7/PSW_I=0 - Disable the world.
