I am facing one issue with this patch. gdb can not analyze the
resulting kernel core file. Looks like gdb treats vmlinux differently if
ELF header type is "ET_DYN". It reads the symbol values incorrectly.
For example, symbol value of "panic_timeout" is 0xffffffff808a1fa8 but
gdb somehow things that it is 0xffffffff008aaebf. Looks like it is
performing some relocation.
I am using GNU gdb Red Hat Linux (6.5-5.fc6rh).
Thanks
