Hi Leon,

I'm not really sure about what is the issue here, but maybe a different
configuration or a missing dependency.

If you need any data about how to reproduce it in qemu, all data should
be in the build, particularly in the "Write config" step:
https://autobuilder.yoctoproject.org/valkyrie/api/v2/logs/5139973/raw_inline

So basically:

SDKMACHINE = "x86_64"
TEST_SUITES = 'ping ssh ptest'
SANITY_TESTED_DISTROS = ''
EXTRA_IMAGE_FEATURES ?= 'allow-empty-password empty-root-password 
allow-root-login'

bitbake-config-build enable-fragment machine/qemux86-64
bitbake-config-build enable-fragment distro/poky

bitbake core-image-ptest-python3-pyzstd
bitbake -c do_testimage core-image-ptest-python3-pyzstd

Please tell me if you have any issue reproducing the failure.

Thanks,
Mathieu
