Subject: Kernel crash with lspci -vv and SAS Controller LSI Logic / Symbios
 Logic MegaRAID SAS 9240

Hi folks

While trying to list Informations about the PCI Devices using lspci -vv 
the Output stops at the SAS Controller (LSI Logic / Symbios Logic 
MegaRAID SAS 9240 rev03) (probably just before the "Kernel driver in 
use" Line) and the system completly freezes. Listing the PCI Devices 
with only lspci -v works though.

Vanilla Kernel: Linux version 3.4.4 (gcc version 4.5.3 (Gentoo 4.5.3-r1 
p1.0, pie-0.4.5) ) #1 SMP Mon Jul 16 13:13:04 CEST 2012

ASUS RS700-E6-ERS4 rev. 1.xxG with ASUS Mainboard Z8PS-D12-1U with two 
Xeon E5645 2.40GHz and 12 x 8GB DIMM

AMI BIOS Version: 1201
