PROBLEM:  (QAR 48650, QAR 54414)    (Patch ID: OSF375-191)
********
This patch fixes the following problems that occur on AlphaServer 1000A 4/233 
and 4/266 systems.

o  If a machine check occurs on an AlphaServer 1000A 4/233 or 4/266, the
   register data written to the binary.errlog will show zeroes in
   all registers when viewed with DECevent.

o  If a correctable memory error occurs, the system panics with a kernel
   memory fault.  The kernel memory fault occurs in procedure bcopy(),
   called by kn22a_proccorr() from source file kn22a.c.
