good - it's not an SMP box :)

sorry for any confusion. the box I *was* able to upgrade to  
RELENG_6_2, and reported in last the email with the dmesg output is  
not SMP. all five HP DL3xx boxes (two of which *are* SMP) show  
exactly the same behaviour irrespective of being SMP or UP. none of  
them have polling enabled.

best.
