QA:Testcase Kdump Func Halt

Setup

1. Install Fedora 17 on your machine
2. After system installed, check if kexec-tools kernel-debuginfo and crash is installed via

   rpm -q kexec-tools

   Or via yum

   yum install kexec-tools

3. Reserve crashkernel for kdump by grubby 

   grubby --args="crashkernl=128M" --update-kernel=$(grubby --default-kernel)

   Reboot system and check /proc/cmdline

   cat /proc/cmdline | grep "crashkernel"

4. Edit /etc/kdump.conf. This is an example:

 :

    ext4 /dev/mapper/vg_dhcp6558-lv_root 
    kdump_post /bin/kdump-script
    extra_bins /usr/bin/crash
    extra_modules twofish-x86_64

1. Apply changes and start kdump via service kdump restart

How to test

1. Trigger crash via:

   echo c > /proc/sysrq-trigger

Expected Results

1. Test failed if

   cat /proc/cmdline | grep "crashkernel"

   got nothing means reserve crashkernel memory failed
2. Test failed if restart kdump failed
3. Test suspend if rpm packages couldn't be installed
