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 . Truncating head block from 0x3338. [ 2.736211] XFS (dm-0): failed to locate log tail [ 2.736220] XFS (dm-0): log mount/recovery failed: error -74 [ 2.737130] XFS (dm-0): log mount failed [ 2.738982] mount (1113) used greatest stack depth: 11040 bytes left [ [1;31mFAILED [0m] Failed to mount /sysroot. 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 |
