[Kernel-packages] [Bug 1818645] Re: Ubuntu18.04.01: [Power9] power8 Compat guest(RHEL7.6) crashes during guest boot with > 256G of memory (kernel/kvm)
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 'verification-needed-bionic' to 'verification-failed-
bionic'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

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, too.
** Changed in: linux (Ubuntu)
Status: New => Fix Released
** Changed in: ubuntu-power-systems
