Yes, I noticed that. This disk is in an LVM and managed by Cinder. So it's not used by the operating system itself. There are lots of lv on it for Linux virtual machines on KVM. I'm not sure if it's the disk hardware issue or just a software problem, e.g. an iscsi target management issue. Can we tell it's a h/w problem based on that message? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1662187 Title: apt-get upgrade hung when it comes to update initramfs Status in Ubuntu on IBM z Systems: New Status in linux package in Ubuntu: New Bug description: ---Problem Description--- apt-get upgrade process is hung when it comes to update the initramfs and it never finishes with any error messages. So I have to kill the process and restart it. But the system asks run 'sudo dpkg --configure -a' to correct the problem if I run 'apt-get upgrade' again.
