[Crash-utility] problem with crash on upstream kernel cores

[Josef Whiter]

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

WARNING: Because this kernel was compiled with gcc version 4.1.1, certain
         commands or command options may fail unless crash is invoked with
         the  "--readnow" command line option.

[root at 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
