Comment 16 for bug 1552551

The problem still exists in 4.7.0rc3 and rc4, along with a few new messages I've never seen before:

At boot, on screen (slowly twice) before X is up: "AAC: Host adapter dead -1" (at modprobe perhaps)

This message seemed to predict the comlete lack of an sdb device, only the SATA laptop hard drive I installed 16.04 onto to test shows up as sda. Reboot performed.

Now (unlike previous kernels), the AAC is sda and the SATA HD is sdb, and I've never seen the BLINK or panic lines before. I'll still try to test rc1, I had to reload to recover my initramfs config and haven't fixed the rc1 kernel yet.
