Example 3–49 shows reports sent to the SCM over the console serial bus when
an unexpected fault occurs during SROM/XSROM testing.
The system is a four QBB system.
The system faults and is detected by the PSM.
Test 34 subtest 5 was running at the time of the fault.
Despite the fault the SCM attempts to bring up the system.
Faults are catastrophic.
The HPM in the hierarchical switch is reset.
The PSMs in the QBBs are reset.
As power-up continues, other tests hang.
In this case, test 34, Local Soft QBB ID Configuration, hung during subtest 5,
writing soft QBB ID to GPA_INIT_ID register. While not a great deal of
information to go on, one might suspect the global port on QBB0 since the
GPA_INIT_ID register is on that module.
