[Kernel-packages] [Bug 1836153] Comment bridged from LTC Bugzilla
--- Comment From cborn...@de.ibm.com 2019-09-03 14:58 EDT--- This still has the verification-needed-xenial tag. Will this be backported or can we remove that tag? xenial-proposed does not seem to contain a kernel update and a backport to xenial was not requested.

I can confirm that the KVM part (this bugzilla) works fine with
a. this kernel from proposed
b. qemu from
https://launchpad.net/~paelzer/+archive/ubuntu/bug-1836154-s390x-hwmodels/+packages
Now. The kernel in proposed has a bug which prohibits this kernel to be
released.
dmesg is flooded with

messages. Looks like you picked an upstream patch and missed several followup
patches in that area.
Thjis is around commit e12e4044aede97974feb7f0ed726a5179a32 ("s390/mm: fix
mis-accounting of pgtable_bytes") and later patches on top of this.
(This is independent from the KVM changes which are working perfectly
fine).

[Test Case]
* need to be tested by IBM on pre-rel. hardware or simulator
[Regression Potential]
* The regression potential can be considered as low since these
changes are limited to arch/s390
* changes are in support for new and upcoming hardware and shouldn't
affect existing s390x systems
[Other Info]
* the first 2 commits are the key ones, the other 7 are needed to make
them applly cleanly
* these patches are already all included in upstream kernel 5.2, hence
they are in eoan's kernel 5.2
* qemu package SRU in LP 1836154 complements this SRU - for testing
