controllers based on the LSI Logic / Symbios Logic SAS1064ET PCI-Express Fusion-MPT SAS
The mptsas driver loaded is:
SAS1064ET PCI-Express Fusion-MPT SAS (MPTSAS, 3.04.07)

I don't even see a LSI SAS 3041E-R on the LSI product list on www.lsi.com
I do see the 3041X-R, and a 3081E-R, and they both use the 1064 drivers.
