I had migrated the Server from Debian 11 to Debian 12 on Dec 11th 2023.
The kernel version provided by Debian 11 at that time was 5.10.197. I
can't remember having seen a frozen nfsd with this version.

Since Dec 11th I had these kernels in use (all provided by Debian):

6.1.66 linux-image-6.1.0-15-amd64
6.1.69 linux-image-6.1.0-17-amd64
6.1.76 linux-image-6.1.0-18-amd64
6.1.85 linux-image-6.1.0-20-amd64
6.1.90 linux-image-6.1.0-21-amd64

These are all "upstream" version numbers. The second column lists
Debian's package names.

AFAIR nfsd got stuck only on the 6.1.90 kernel (installed and booted
on May 18th, first time freeze on May 26th). But I've got a weak
memory in cases like this. I haven't found older kernel log files.

Please remember that I have seen a frozen nfsd only 3 times since
May 26th. Its not easy to reproduce.
