------- Comment From pa...@de.ibm.com 2018-08-31 05:28 EDT------- Colin, thanks for the input. Based on Christians realization, that your hypervisor may have been 16.4 all along, and on the qemu version you stated, I managed to reproduce the bug with upstream tag v2.5.0. From there I bisected to commit e32652f7594 "virtio-ccw: respond to READ_STATUS command" (which seems to fix the problem). I still have to figure out the whys tough.
Anyway, you should stop seeing the bug with QEMU 2.8 (or more recent).
