Hi All​


We've reproduced a 1-1 Kexec failure on Fedora 23 ppc64le Bare Metal Install (Stock OS). We also tested it on live host OS and also observed that it fails too.  


Here's all the stuff we tried:

​Fedora 23 
​Failure
​Fedora 23     
​Ubuntu 15.04
​Failure
​Fedora 23
​Ubuntu 15.10 
​Failure


Kexec works on following ppc64le Stock Host OS:  Ubuntu 15.10, 15.04, CentOS 7.2 


Kexec Fails on following ppc64le Stock Host OS:    Fedora 23 , Debian 8.3 OS


Logs: 

System hang happens with random logs (More often with no logs at all). I've attached couple of snippets of logs we were able to obtain. 


Here are steps to reproduce:
a.

Install kexec-tools

b. Run: 

kexec -l vmlinuz —initrd=“initrd.img” —command-line=`cat /proc/cmdline`

c. Run:

kexec -e

d.

Host Console hangs indefinitely, without providing ability to get any logs.


Here are some details on Fedora Kernel and OS:
