Package: src:linux
Version: 4.9.13-1
Severity: normal

Upgrading from 4.4.0-1 to 4.9.0-2 broke Kerberos security for NFS, at 
least as a server.

kernel: CPU: ARMv7 Processor [413fc082] revision 2 (ARMv7), cr=10c5387d
kernel: OF: fdt:Machine model: Cubietech Cubieboard

Unless I blacklist the sun4i_ss module then mounting the exported file
system will not work and the kernel will log:

kernel: alg: skcipher: Test 1 failed (invalid result) on encryption for cts(cbc-aes-sun4i-ss)
kernel: 00000000: 4b 10 75 fc 2f 14 1b 6a 27 35 37 33 d1 b7 70 05
kernel: 00000010: 97

http://sunxi.org/Cryptographic_Hardware_Accelerators says that CTS mode 
is not even implemented on A10 CPUS.
