[Crash-utility] Problem opening core file.

[Rohit Persai]

Greetings,

I am trying to open a core file but getting following error. I am sure 
that I am using right kernel + kernel-debuginfo package. As following 
command on crash log shows version on kernel in use.
# cat crash-log | grep -i 2.4.21
EIP is at check_pgt_cache [kernel] 0x19 (2.4.21-47.ELsmp)

# crash /usr/lib/debug/boot/vmlinux-2.4.21-47.ELsmp.debug 
/boot/vmlinux-2.4.21-47.ELsmp case_1843132_vmcore

crash 4.0-6.3

Question: Why am I getting following message if I am using right set of 
packages.
crash: /usr/lib/debug/boot/vmlinux-2.4.21-47.ELsmp.debug and 
case_1843132_vmcore do not match!

Any help would be greatly appreciated.
Rohit.
