John -

In the Service Functions Reference,
see page 190 for a general description of B9xx xxxx:
http://publib.boulder.ibm.com/iseries/v5r2/ic2924/books/sm09/y4459026.pdf

and you'll see:
B9xx xxxx Operating system machine check (See iSeries OS/400 Diagnostic
Aids)

A Google search on "iSeries OS/400 Diagnostic Aids" found this:
http://www-912.ibm.com/s_dir/slkbase.NSF/0/29dac611943664fe862565c2007d4ead?OpenDocument&ExpandSection=1


Did you search the midrange.com archives?

The "iSeries OS/400 Diagnostic Aids" appears to be
an expensive book available only in hard-copy.  See here:

Finally, according to this posting, an OS reload may be in your future:
