Hi Developer,

Our test environment setup is as follows:
Power 8 system, using VIOS, we partitioned it into 10 LPARs, one of the LPAR is installed with Ubuntu OS.

(130) root @ devops4p10: /root
# uname -a
Linux devops4p10 4.17.0-041700rc2-generic #201804230622 SMP Mon Apr 23 11:04:06 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux

The ubuntu level is
(130) root @ devops4p10: /root
# cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu Bionic Beaver (development branch)"

Currently, the system has vio uevent error logs:
