Bug#923524: installation-reports: buster on s390x qemu: ssh key generation hangs; repeated message "BUG: non-zero pgtables_bytes on freeing mm: -16384"



Package: installation-reports
Severity: normal

I tried to install Debian s390x on a qemu VM using command lines based on
<https://wiki.qemu.org/Documentation/Platforms/S390X>.

A stretch installation hasn't finished yet but appears to be heading for
success, using this command-line:

qemu-system-s390x \
-machine s390-ccw-virtio \
-cpu max,zpci=on \
-m 4096 \
-nic bridge,br=virbr0,model=virtio \
--cdrom ~/incoming/debian-9.7.0-s390x-netinst.iso \
-kernel ~/incoming/kernel.debian.stretch.s390x \
-initrd ~/incoming/initrd.debian.stretch.s390x \
-drive file=/home/smcv/tmp/virt/s390x.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=unsafe \
-device virtio-blk-ccw,devno=fe.0.0001,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1,scsi=off

(*.debian.stretch.s390x are from
<http://ftp.debian.org/debian/dists/stable/main/installer-s390x/current/images/generic/>,
and virbr0 is the default bridge behind NAT created by libvirtd, with
192.168.122.x addresses.)

However, an installation of the current buster netboot image with a
similar command-line fails. The step that should generate a SSH host key
hangs at 0% progress; perhaps this is related to insufficient entropy
in the kernel?

I also noticed repeated kernel messages "BUG: non-zero pgtables_bytes
on freeing mm: -16384" which are probably a bad sign.

I used:

script -c "\
qemu-system-s390x \
-machine s390-ccw-virtio \
-cpu max,zpci=on \
-m 4096 \
-nographic \
-serial mon:stdio \
-nic bridge,br=virbr0,model=virtio \
--cdrom ~/incoming/debian-buster-DI-alpha5-s390x-netinst.iso \
-kernel ~/incoming/kernel.debian.testing.s390x \
-initrd ~/incoming/initrd.debian.testing.s390x \
-drive file=/home/smcv/tmp/virt/s390x-testing.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=unsafe \
-device virtio-blk-ccw,devno=fe.0.0001,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1,scsi=off \
" ~/s390x.typescript

and got the attached typescript. This is hopefully reproducible on any
sufficiently capable laptop/desktop, with appropriate adjustments to
filenames and the emulated network card.

(*.debian.testing.s390x are from
<http://ftp.debian.org/debian/dists/testing/main/installer-s390x/current/images/generic/>
as of today, and again virbr0 is the default bridge behind NAT created
by libvirtd, with 192.168.122.x addresses.)

How do s390 porters normally test debian-installer? Am I right in assuming
that the answer probably doesn't involve a $75K mainframe?
