Comments

• This APAR has been seen to cause overlays to pages of storage,
  especially ESQA storage, whose address corresponds to the first
  word of a PSW.  For example, overlays have been observed to the
  page at 070C0000 in storage, the page at 078D1000 in storage,
  etc.  Since these storage addresses tend to be within above the
  line SQA where various critical system control blocks live, the
  symptoms of the overlay can be unpredictable, and the impact can
   be significant.  In the case of an overlay at one of these
  "PSW-like addresses", the overlay content typically has the hex
  byte value X'E8' at offset +X'31' into the page, and many zeros
  beginning at offset +X'54' into the page.
