I think Gary's right. According to the HPSWINFO file on my 6.5 PP3 systems,
it's MPELXJ2A:

** NOTE: ITRC shows this patch has been superceded, latest patch is
MPEMX77A. Other MPE versions (6.0, 7.x) will have slightly different patch
ID's. **

The ITRC web site description for patch MPELXJ2A says:

If I had to guess, I would say the same problem affected SYSINFO's IOMAP
routine. If so, it appears to have been fixed.
