The test is 'grab a Fedora 32-bit nightly boot.iso (network install) image and try and boot it'. You can watch it failing in glorious video technicolor here (the video is sped up, but you can step through frame- by-frame to catch the errors): https://openqa.happyassassin.net/tests/4631/file/video.ogv you can download an affected image here: https://kojipkgs.fedoraproject.org/mash/rawhide-20150911/rawhide/i386/os/images/boot.iso I guess strictly speaking we're only sure it fails when booted in a qemu-kvm VM, but I think we did hit the previous incarnation in bare metal testing too (so far I haven't tried the 4.3 incarnation on metal). we don't keep the nightly ISOs around forever, but it'll be there for at least a couple of weeks. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net
