Several crashes during backup to NFS after upgrading to Proxmox VE 6.4

Hello,

We experienced three kernel crashes during guests backup of two distinct Proxmox VE fully-updated 6.4 hosts running on 5.4.114-1-pve Linux kernel. Backups are using the stop mode and a NFS mount. Other hosts running Proxmox VE 6.3 on Linux 5.4.106-1-pve did not triggered the problem.

I've taken the two enclosed screenshots of the host console after the crash. They seem to exhibit the same fib_get_table kernel method, but this is where my kernel debugging knowledge stops...
