Install and boot of the FIPS kernel packages failed with disk not found errors on amd64. This was also observed on standard Ubuntu kernels prior to 4.11.0. FIPS ------ 1. linux-image-4.4.0-1002-fips <-- FAIL 2. linux-image-4.4.0-1006-fips <-- FAIL UBUNTU ------------ 1. Bionic kernels all WORK 2. Artful kernels: Ubuntu-4.11.0-1.6 <-- WORKS Ubuntu-4.10.0-26.30 <-- FAILS 3. Xenial kernels: Ubuntu-hwe-4.11.0-12.17_16.04.1 <--- WORKS Ubuntu-hwe-4.10.0-43.47_16.04.1 <--- FAILS Ubuntu-lts-* <--- ALL FAIL Ubuntu-4.4.0-* <--- ALL FAIL We have narrowed down the window to be: 4.11.0-1.6 (custom build) <--- WORKS 4.10.0-43.47~16.04.1 <-- FAILS Also works: https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11/linux-image-4.11.0-041100-generic_4.11.0-041100.201705041534_amd64.deb Symptoms ------------- System cannot find the root disk and drops into an initramfs shell: mdadm script local-block "CREATE group disk not found" "Gave up waiting for root device.

(initramfs)_ There does not appear to be any workaround so far. The disks are encrypted SSDs.
