[Crash-utility] Throw read error on vmcore produced by ARM soc.

Hi, list. I use crash-utility to analyse crash dump core from ARM soc. When I execute command below, I get the error "crash: read error: kernel virtual address: c0c1e040 type: "first vmap_area va_start"". I also test it by gdb. It works fine. The Linux kernel's version is v3.0.8. hfli@pc1935:~/work/crash-utility$ ./crash vmlinux Vmcore crash 6.1.4 Copyright (C) 2002-2013 Red Hat, Inc.
