Thanks,

Retest by latest kernel kernel-4.17.0-1.fc29, crashkernel=160M works well both local and nfs dump. So, we can close this bug as NOTABUG. This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle. Changing version to '29'. It should be not a bug, please increase the crashkernel memory size for kdump to work |
