Symptoms
On rare occasions, a root file-system inconsistency or partial corruption on OPL domains can avoid domain from booting, and generate errors during boot attempts that can be misleading and lead to unnecessary hardware replacement.
BERR and/or BTO events can be reported during boot even if no platform hardware is actually faulty.
No degraded or faulted HW should be marked by XSCF for this Document's solution to be applicable.
An example is reported below, collected on Domain 0 on a M4000 platform
