Latest "fix" for issue is to disable C-states under processor configuration in bios. this also fixes problems in other OS's (eg. in solaris)
Dell has been aware of the issue for months without real fix, just workarounds.

Indeed the R710 has BCM5709 and the R410 has BCM5716, but both (at least, 
the ones I have) are subject to similar issues, even under medium load. 
With disable_msi=1, they are both solid. CentOS 5.4.
