The reason for the panic is hidden in this one line of the kernel logs:
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
The init process is killed by SIGSEGV (signal 11 = 0xb).
I would suggest you look for data corruption bugs in the RX path. If
the code is fetched from the NFS mount then a corrupt RX buffer can
trigger a crash in userspace.
