Bryan,

I seem to remember that an incorrect installation order
could drive to problems like the one you're experiencing
(or better, I've read some articles posted here stating
that if the installation order is not fully honored, you
could have SMP problems even with RS505A and OSS497C
installed). 

From memory, the installation pattern should be :

	- install the base OS 
	- install the SMP package but DO NOT RELINK (if possible)
	  or reboot
	- apply patch RS505A
	- relink + reboot
	- apply patch OSS497C

Hope this helps !

Best,
Roberto
