I'm assuming that you are running version 2.2.x (included with RH8).. Have you tested 3.0 (wait until 3.0.1 if you haven't yet since there are a lot of bug fixes in it).
What is the smbd process doing ? Trying running strace or get a backtrace in gdb to find out where it is spending its time.

Probably fctnl() calls when looking up data in a tdb. Find out which tdb (withe look in /proc/<pid>/fd to match the file descriptor or us lsof).
Also check the network traffic at this point.

Are you servning printers by chance? If so have you set 'disable spoolss = yes' ? I've seen high CPU utilization cases in relation to this param.

use mii-tool and check the duplex settings. And any hardware can have problem no matter what the price tag says :-)

Chgeck you routers. Maybe they are getting overloaded or are dropping packets.
