The only way you can do a <ctrl>-B on a D/R class is *if* it has a
A3262-69311 card which is the ups/modem/remote access port.  It has a
switch on the back that has to be in the service mode for the <cntl>-B
to work.  Most of the higher end D/R's have the card and for the lower
models it was and optional part.  So if you can't do a <cntl>-B, check
the back of your machine and look for a card that says access port on
it with a little black 2-way switch on it with 2 positions (normal and
service).  All the service position does is allow remote access and
enable the <cntl>-B service processor functions.

CBF0-HPMC occurred-starts normal HPMC process
5002-Path error
7D03-Memory MSI read error-says maybe due to a software error
5508-Broad error-part of the hpmc handler
5408-Broad error-part of the hpmc handler
CBFB-Branch to OS HPMC-Normal HPMC process

I'm still trying to locate my I/O troubleshooter.  I'll get back to you
later on that.  I would say that the MSI read error is generated by the
apt-get and is causing the problem.  That's only a quick guess on my
part since I've got to run and replace a system card in an R Class
right now.
