We have 21 SMP Intel based PC's running RedHat 6.2 with all the latest
updates applied.  We noticed the warning about possible SMP issues in the
default kernel that comes with 6.2 and that encouraged us to update.  Since
the updates, about 1 month ago, we have been plagued with kernel panics of
a very random nature.  These 21 machines are only 21 of 160 boxes we have
in a Beowulf Cluster.  The unique value of these 21 nodes is the fact that
they are SMP nodes.  No other UniProcessor node seems to suffer from these
instabilities.  We are averaging a kernel panic every couple of days on the
21 SMP nodes.  I'd like to submit the kernel panic info directly to you and
the kernel list but other then hand coping the screen I have no idea how to
caputre that info.
