Hello,
the slow verification of this blocks the more important/urgent fix of bug
1749393 that we'd really would want to get released before Christmas. I know
that FHeimes has coordinated this to be tested within IBM - any chance to get
this completed in the next few days?

Thanks, I agree and I guess if it really is a problem (I think not) then
the SRU team will speak up on review.

I understand you want to stage this fix in Hirsute via block-proposed as
by looking at Hirsute alone the benefit/cost of the SRU is not high
enough, still doing this will mean that there will be a (small)
regression for users upgrading from Focal to Hirsute.
OTOH if we look at Focal and Hirsute

Thank you for the clarifications!
Then I'd say we can piggyback it onto another upload !IF! upfront you
could spent the cycles to confirm that the test builds really give you
what you'd want/need in Focal and Hirsute.
Until then - I'll mark this Won't Fix

Ok, emulation it shall be then ...
Finalized test steps:
1.
On x86 get an emulated s390x guest the way you prefer
Example with uvtool + modifications:
$ sudo apt install qemu-system-s390x
$ uvt-simplestreams-libvirt --verbose sync --source
http://cloud-images.ubuntu.com/daily arch=s390x
Hi again,
I know it is prio-low for everyone, but still thanks for your patience!
Plenty of other things now finally are out of the way, so I tried to test the
current broken'ness of this before starting a SRU.
1. Create a s390x KVM guest, for example via, but not limited to:
$ uvt-kvm create

Thanks for the report, it LGMT and makes sense - although uretprobe inside of
s390x emulation is super rare and therefore not urgent IMHO.
I'd make this part of the qemu 6.0 (it is applied upstream after that) that
I'll prep for Ubuntu 21.10 and once that is completed consider SRUs.
If you are
@IBM Please could you provide a more step-by-step test case?
That would allow us to verify the package once the fix got picked up.
