Hi all,

taking a closer look at the log files I find an entry EPC which is
supiciously similar in all of the crashes I described in the earlier mail.
What does EPC mean? and does this support the thesis that the chips have to
be replaced?
EPC                       x802465FC
EPC                       x802464D4
EPC                       x8024459C
 (the EPC lines are greped out of the uerf error 101 and example of the
entry follows.
