I tested by upgrading my kernel using "apt-get dist-upgrade " command. I tried the same scenario that is mentioned in the bug after upgrade.
This is the state on my guest root@ubuntu:~# dpkg --list | grep linux ii libselinux1:ppc64el 2.2.1-1ubuntu2 ppc64el SELinux runtime shared libraries ii linux-headers-3.13.0-0 3.13.0-0.15 all Header files related to Linux kernel version 3.13.0 ii linux-headers-3.13.0-0-generic 3.13.0-0.15 ppc64el Linux kernel headers for version 3.13.0 on PowerPC 64el SMP ii linux-headers-3.13.0-1 3.13.0-1.16 all Header files related to Linux kernel version 3.13.0 ii linux-headers-3.13.0-1-generic 3.13.0-1.16 ppc64el Linux kernel headers for version 3.13.0 on PowerPC 64el SMP ii linux-headers-generic 3.13.0.1.3 ppc64el Generic Linux kernel headers ii linux-headers-virtual 3.13.0.1.3 ppc64el Transitional package. ii linux-image-3.13.0-0-generic 3.13.0-0.15 ppc64el Linux kernel image for version 3.13.0 on PowerPC 64el SMP ii linux-image-3.13.0-1-generic 3.13.0-1.16 ppc64el Linux kernel image for version 3.13.0 on PowerPC 64el SMP ii linux-image-virtual 3.13.0.1.3 ppc64el This package will always depend on the latest minimal generic kernel image. ii linux-virtual 3.13.0.1.3 ppc64el Minimal Generic Linux kernel and headers ii util-linux 2.20.1-5.1ubuntu11 ppc64el Miscellaneous system utilities root@ubuntu:~# But still I am seeing the same issue again on my guest.
