* Protected Errors SW to determine panic or not, forgivable for safe access.
* Set when SW determines this error is forgivable during safe acc.
* No-panic Errors that don't directly result in panic'ing the system.
* No-Error When an interrupt occured and no errors were seen
* Fabric Scan Indicates that fabric scan will determine final severity of a
