Right you are. Here is the corrected output: $ modinfo -k 4.12.0-1-amd64 xts filename: /lib/modules/4.12.0-1-amd64/kernel/crypto/xts.ko alias: crypto-xts alias: xts description: XTS block cipher mode license: GPL depends: intree: Y vermagic: 4.12.0-1-amd64 SMP mod_unload modversions Which is substantially similar to the original output, but I'm posting here in case you notice any important differences. > So the ecb module is not included. > Can you check that the 4.12 kernel has an ecb module ? > > ls /lib/modules/4.12.0-1-amd64/kernel/crypto/ $ ls /lib/modules/4.12.0-1-amd64/kernel/crypto/ecb.ko /lib/modules/4.12.0-1-amd64/kernel/crypto/ecb.ko > > As a workaround, my idea is to force inclusion of the ecb module in the > initramfs by listing it in /etc/initramfs-tools/modules and rebuilding > the initramfs with > > update-initramfs -u -k 4.12.0-1-amd64 I've done as you suggested and I'll let you know in my next reply if it worked. Assuming it does, does this mean that I'll have to set this manually from now on or does in indicate something in the auto-configuration when the new kernel installs and/or runs? With many thanks again
