Caused by a slight change in the crash/gdb-7.0 exception handling.
Simple fix attached...
The patch fixed the problem on my dump file. It now prints:
crash-5.0.fix> struct bnx2 0xffffc90006b000cf
struct bnx2 struct: invalid kernel virtual address: ffffc90006b000cf
type: "gdb_readmem_callback"Cannot access memory at address
0xffffc90006b000cf
crash-5.0.fix>
