Hello IBM, Could you please verify if the Bionic kernel currently in -proposed fixed the issue as expected? Thank you. -- 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/1818645 Title:

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag

Since the fix is already included in the disco kernel I'm changing the root 'linux (Ubuntu)' entry (that is usually used to track the current development release kernel) to Fix Released. And because the bionic entry is Fix Committed I adjust the project entry and change it to Fix Committed,

Assuming that this happens with all guests with more than 256GB of memory, since it's a KVM host kernel side issue. ** Also affects: ubuntu-power-systems Importance: Undecided Status: New ** Changed in: ubuntu-power-systems Importance: Undecided => High ** Changed in:
