Hi,
 
I have been working on back-porting kexec/kdump functionality from 2.6.13 vanilla kernel to RHEL4, Update 2 kernel (version 2.6.9-22).
 
As part of that, when I try to invoke "crash" on a vmcore generated, I get the following error in "crash" tool:
 
[root crash-4.0-2.23]# ./crash /boot/System.map-2.6.9-kdump-1 /usr/src/redhat/BUILD/kernel-2.6.9-kdump-1/linux- 2.6.9/vmlinux /root/vmcore
 
crash 4.0-2.23

I tried with both crash-4.0-2.15 as well as crash-4.0-2.23. Same result.
- Should I be re-building crash as part of the back-port?
- Is crash capable of handing vmcore's generated by kdump?
- Can someone suggest how I can make progress to get crash to work for this?
 
Thanks,
