NFS mount under macOS 10.13.2 reboots the Mac

I have been mounting an NFS share under OS X resp. macOS successfully for years until macOS 10.13.1, but it fails under 10.13.2.

I am trying to do it from the command line: sudo mount -t nfs -o resvport,noacl,nolocks,locallocks ... and get a reboot of my Mac (reproducibly). Without the "revsport" parameter I get the error "operation not permitted". If I try to do it from the finder gui I just get an unspecific error.

Any suggestions would be greatly appreciated!
