[Crash-utility] WARNING: cannot access vmalloc'd module memory

I'm seeing the following warning when I run crash against a kdump vmcore 
  created on an i386 smp system with 4 GB RAM.

	WARNING: cannot access vmalloc'd module memory

The relevant version #s are:

	crash 4.0-25
	kernel 2.6.16.14-6-bigsmp

crash -d2 shows the following:

crash: read error: kernel virtual address: f8c6f680  type: "module struct"
WARNING: cannot access vmalloc'd module memory

The vmlinux and vmcore do match.  I also tried specifying the System.map 
file with the same result.

Anybody know why this is occurring?  What should I check next?

Thanks,
