ECO KIT SUMMARY:

An ECO kit exists for CTDRIVER.EXE on OpenVMS Alpha V6.1 through
V6.1-1H2.  This kit addresses the following problems:

Problems Addressed in the ALPRTPA01_061 Kit:

  o  If there is an I/O error, then there is an attempt to remove the
     current Interrupt Request Packet (IRP).  If there is a buffer
     associated with this IRP, then the buffer is deallocated.  But,
     before the IRP itself is removed, the caller is returned and the IRP
     is left hanging.  The user might see this as a loss of nonpaged
     pool.  Over a period of time this could exhaust the pool in the
     system.

  o  The user will see this in several different ways depending on how
     the registers R9 and/or R10 are being used.  The result could be a
     process hang or system crash.
