Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009
Rebooting in 5 seconds..
This happened on three different systems. On a similar system with just
one CPU in a socket it boots fine. The last Kernel of this series I tried
was 2.16.48 and that worked fine.
Any idea what is wrong? In case it is useful I have attached my kernel
config.
Regards,
Holger
