While trying to install F17 prega3 ppc64 by following below scenario , it threw BUG at cpu soft lockup and got stuck with Call trace. Installation did not proceed further.

--- What steps I followed ---
This system has one native disk (sda) and four multipath disks attached.

step1) Install f17 prega3 ppc64 on sda (native disk) successfully
step2) Install f17 prega3 ppc64 on one of the multipath disk 
step3) After installation on multipath disk , booted with the installed multipath disk , which dropped me to the grub> prompt
step4)Tried to reinstall the system and booted with virtual DVD attached 
         - Choose to go with basic storage installation
         - Removed all the partitions from the sda (native drive)
         - Removed swap file system from the earlier multipath installed disk
Step5) Forcefully rebooted the system without any installation.
Step6) booted from the virtual DVD again , and went for the re-installation by providing following boot command line parameters 
     boot: linux ip=9.3.110.175::9.3.110.1:255.255.255.0:xxx.xxx.xxx.com:eth0:none nameserver=9.0.9.1 debug rd.debug sshd vnc

After sometime it got Call trace and BUG at soft lockup .

Attached install log captured from the console "console-installation-log.txt"
