Just thought I’d mention it here, the latest testing 20220227.2.1 with the 5.16.x kernel breaks NFS with QNAP nfsd.
As mentioned here
2055362 – NFS mount hang on kernel 5.16.10
FS#73860 : Linux i5 5.16.10-arch1-1 kernel: NFS don't mount anymore
6f283634 / 1976b2b3 breaks NFS (QNAP/Linux kNFSD) — Linux NFS
Right now I’m trying to change back to stable stream to give me a week, other than that i’m not sure how to workaround this.
