It may also be worth making sure you're using the latest bnx2 version. 
$(modinfo bnx2) should give you that, the latest one being 1.7.6b3.

I've been using those PE1950 a while, and had my share of weird issues with 
them, including complete kernel panics on high traffic load. Upgrading to the 
Dell-provided bnx2 version proved helpful. 

If you use SuSE or a Redhat-ish distro, the Dell Linux repository 
<http://linux.dell.com/repo/hardware/> may be useful, and upgrading the module 
version would be extremely simple to handle with the help of DKMS.
