Error# = LMNX
X = 1 CE testing N = 1 No IRQ<0>(CE) or IRQ<4> (UCE) interrupts posted to the CPU
X = 2 UCE testing N = 2 Incorrect IRQ interrupts posted to the CPU
M = 0 QSD Error Summary CSR (CPUx_CE/UCE_SUM) was correct
M = 1 Invalid CPU ID in CPUx_CE_SUM or CPUx_UCE_SUM
M = 2 No QBB_NUM bits set in CPUx_CE_SUM or CPUx_UCE_SUM
M = 4 Incorrect QBB_NUM set in CPUx_CE_SUM or CPUx_UCE_SUM
M = 8 More than one QBB_NUM bit set in CPUx_CE_SUM or CPUx_UCE_SUM
L = 1 FRU1 is likely the QSD, QSD->CPU path, or CPU
L = 2 FRU1 is likely IOA, QSDy, or IOA->QSDy path (where y=CPU# of Cpu running the test)
L = 4 FRU1 is likely the MPA, WFJ, or MPA->WFJ path
FRU2 is likely the WFJ, IOA, or WFJ->IOA path
