Looking at oops message attached to bug14579, I am still unable to map anything which might be related to LSI driver, in sort I am not getting any pointers related to fusion driver from OOPS message . Better way to provide Oops will be console redirect.

I have attached latest fusion driver version 3.04.13 for upstream kernel.
You can run *compile* script inside fusion folder to compile it.
You have to copy *.ko to /lib/modules/`uname -r`/ and create mkinitrd once again to reflect driver update in mkinitrd.
