I've been struggling with a kernel panic during enumeration of a Rapid IO system.
I am using the AM4140 with Freescale P4080 processor. The Linux kernel'version is 2.6.34.6. I've set riohdid=0 on the kernel command line.But when the OS boots up,the kernel panic as following:

That is a very old kernel. If you're using that old kernel because it's a
tree you got from some vendor, please contact them for assistance.
Otherwise, please try again with the latest kernel.
