Public bug reported:
qemu latest
kernel 5.3.18
I am using a passthrough dasd as boot device, the installment looks fine
and gets into reboot process. However VM could not boot and just hang as
below after that. I have been checking on "s390: vfio-ccw dasd ipl
support" series right now but no clue yet. Could anyone take a look for
it? Thanks.

Can you still reproduce this issue with the latest version of QEMU?
Which kind of guest did you install?
