Description Karel Srot 2011-11-03 09:47:12 UTC

similar to 688700 but valid for all archs, even intel

[root@rhel57 ~]# rpm -q file
file-4.17-15.el5_3.1
[root@rhel57 ~]# file /boot/vmlinuz*
/boot/vmlinuz-2.6.18-274.el5: ELF 64-bit LSB shared object, AMD x86-64, version 1, stripped


+++ This bug was initially created as a clone of Bug #688700 +++

Description of problem:

.qa.[root@s390x-6s-v1 boot]# file vmlinuz-2.6.32-71.18.2.el6.s390x
vmlinuz-2.6.32-71.18.2.el6.s390x: data
.qa.[root@s390x-6s-v1 boot]# file vmlinuz-2.6.32-71.18.2.el6.s390x.debug
vmlinuz-2.6.32-71.18.2.el6.s390x.debug: data


Version-Release number of selected component (if applicable):
file-5.04-6.el6.s390x

How reproducible:

always

Steps to Reproduce:
1. run file on s390x vmlinuz file (compressed kernel image)
2.
3.
  
Actual results:
on s/390x:
file vmlinuz-2.6.32-71.18.2.el6.s390x
vmlinuz-2.6.32-71.18.2.el6.s390x: data

on x86_64:

file /boot/vmlinuz-2.6.32-71.el6.x86_64 
/boot/vmlinuz-2.6.32-71.el6.x86_64: Linux kernel x86 boot executable bzImage, version 2.6.32-71.el6.x86_64 (mockbuild, RO-rootFS, root_dev 0x901, swap_dev 0x3, Normal VGA


Expected results:

something similar to output present on x86_64

Additional info:

This issue seems to be limited to s/390x
