Thanks for very good explanation.
I tried vmlinux.dbg and got
WARNING: could not find MAGIC_START!
crash: ../smp-dbg/boot/vmlinux-2.6.15.7+smp and crashdump.2006-08-15-11-13-23 do not match!
I should mention that I had to patch crash so that it can read all the symbols. I originally
got symbol overflows. e.g crash gave output:
crash: symbol count overflow (__func__.1)
crash: symbol count overflow (__func__.2)
crash: symbol count overflow (__func__.3)
crash: symbol count overflow (__func__.0)
To get "dis -l" to work, should I just compile the vmlinux "-g" and extract the debug
info to .debug file e.g, Like RHEL 3.0 does?
Thanks,
