We experience this problem on all 5.4 releases and occasionally on  
4.10 and 4.11. All systems are Dell 1750's. Looking at the changes  
present in p5, p6 and p7 it seems unlikely that that has caused it,  
but if you have found why this occurs please respond back to the  
list! If you do a serach for SMP and Dell you'll find my older posts  
as well...

Best of luck,
Rutger
