The same kernel works just fine on an IBM Power-8 machine
I suspect the problem I mentioned couple days ago on IRC about network modules on s390x is the same as here.
(In reply to Dan Horák from comment #2) > I suspect the problem I mentioned couple days ago on IRC about network > modules on s390x is the same as here. So my memory was wrong, kernel 4.5.0-0.rc2.git3.1.fc24 fails on s390x with Mounting /sysroot... [ 2.473809] SGI XFS with ACLs, security attributes, no debug enabled [ 2.483961] XFS (dm-0): Mounting V5 Filesystem [ 2.643433] XFS (dm-0): Torn write (CRC failure) detected at log block 0x3328 .

See 'systemctl status sysroot.mount' for details. If reproducable with latest 4.5 kernel I'll open a separate bug report.
Presumably this is working with 4.5.0 GA
