2.6.15-rt16 compiled w/o SMP support has been working fine. On the
same hardware (dual p3) with SMP compiled in I am getting BUGS.
The computer boots fine, and the following (trace at end of email)
occurs after I log into the computer over SSH. Specifically I am
prompted for my password and immediately after I submit my password to
SSH the box goes crazy.
