Dear Yocto team,

Linux kernel image build in Yocto version 2.5  is giving following error.

*Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b*

core-image-minimal image using as a root file system.

*Same kernel recipe build in the Yocto 2.2.2 version is working fine.*

one difference observed in the 2.5 and 2.2.2 kernel build image boot is
build pc name coming as (graco_sm at build) and (oe-user at oe-host) respectively.
Both the Yocto 2.5 and 2.2.2 building in the same pc graco_sm, in 2.5
version taking as oe-user at oe-host, what could be the reason for this ?

2.5 Linux build :
Linux version 4.9.0-rt1 (oe-user at oe-host) (gcc version 7.3.0 (GCC) ) #1 SMP
PREEMPT RT Fri Sep 7 06:53:17 UTC 2018

2.2.2 Linux build :
Linux version 4.9.0-rt1 (graco_sm at build) (gcc version 6.2.0 (GCC) ) #1 SMP
PREEMPT RT Wed Aug 29 19:09:12 IST 2018

For your reference attached the both version kernel boot log files
kernel_yocto_2.2.2.txt and kernel_yocto_2.5.txt.
Attached the linux recipes files.


Kindly help us to resolve this issue.


Thanks and Regards,
