Hello,
I'm having a problem using crash on cores generated by upstream kernels (in this
case 2.6.20). I'm using crash 4.0-3.20, and I've built my kernel with -g.
Whenever I try to open it this is the error I get
[root@rh5cluster2 127.0.0.1-2007-02-23-15:09:25]#
crash /root/linux-2.6/vmlinux vmcore
crash 4.0-3.20

the "--readnow" command line option.
[root@rh5cluster2 127.0.0.1-2007-02-23-15:09:25]# file vmcore
vmcore: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style
the file is definitely a proper core. I used the --readnow option and that did
not help either. Thank you,
Josef
