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

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

[stepping stone GmbH]

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

Xeon E5645 2.40GHz and 12 x 8GB DIMM

PCI Config reads from lspci -vvv don't go through the megaraid_sas
driver itself.

It looks like your system hung up while trying to do a PCI Config read
of Capabilities 0xd0: VPD (Vital Product Data).

I have a 9240 controller, and with kernel 3.5.0-rc1, I can do lspci -vvv :

                Unknown small resource type 00, will not decode more.

Can you reproduce with kernel 3.5.0-rcX ?  I would also try upgrading
your controller firmware.

Dear Adam

It did not work (exact same behaviour) with a newer kernel (3.5-rc7). 
The problem was the firmware. After a upgrade it works; with older 
kernels too. Great thanks and sorry to bother you (all).

Greetings

David
