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