for info:

Seems to also affect linux-lts 5.15.24-1-lts
I run it next to 5.16.10.arch1-1. I have the problem on both kernels.

mount.nfs: mount(2): Protocol not supported

Do you still use NFS v2? That no more supported for good reasons in nfs-utils.
Comment by Christian S. (pepper) - Friday, 18 February 2022, 19:07 GMT
same here... nfs server is a QNAP device. I don't know if it's relevant.
I didn't any error messages.

Probably a duplicate of  FS#73838 . NFS v3+v4 should keep working and not report "Protocol not supported".
Comment by j (BottleNeck) - Saturday, 19 February 2022, 05:28 GMT
after some troubleshooting, trouble exists with V4 but NOT V3.
Comment by Brian BIdulock (bidulock) - Sunday, 20 February 2022, 00:38 GMT
Also here both kernels NFSv4 QNAP.
But just hangs instead of "protocol not supported".

Same issue here with 5.16.10. I cannot seem to find any reports upstream on this..

5.16.9.arch.1 is working fine. (https://europe.archive.pkgbuild.com/packages/l/linux/linux-5.16.9.arch1-1-x86_64.pkg.tar.zst)
Comment by Andreas Radke (AndyRTR) - Sunday, 20 February 2022, 09:00 GMT
If upstream is not aware of this issue it won't get fixed magically. So please post this to the stable/nfs mailing list + kernel bugzilla.
Comment by Andreas Radke (AndyRTR) - Monday, 21 February 2022, 06:50 GMT
Please try 5.15.24-2 from testing repo.
Comment by Brian BIdulock (bidulock) - Tuesday, 22 February 2022, 09:32 GMT
Yes, 5.15.24-2 works! Thank you! Please apply also to 5.16.10.

With Linux i5 5.16.11-arch1-1 It mounts again with version 4.
Thanks
