Public bug reported:
After an upgrade from xenial to yakkety, the system does not boot
reliably. Only 1 boot over 3-4 seems to succeed.
Quite often, the system seems to hang during boot and then drops into an
emergency prompt.
Pressing esc during the boot to show what is going on reveals that there
are processes waiting for the disks to become ready.
This is likely to be related to the specific system configuration, with
a raid array of two disks managed by dmraid (it is an intel fake raid)
and lvm2 on top of it. Most stuff is on it in logical disks, but for the
boot partition that is on a fast ssd, and the root of the filesystem
that is on lvm2 with a physical volume spanning the rest of the ssd.
The very same configuration worked just fine on xenial.
To make the matter worse, it is impossible to boot in "recovery mode" to
get a root prompt, because after you login as root something suddenly
times out and the screen gets messed up (not a graphics card issue, but
pieces of messages popping out here and there, the recovery mode menu
suddenly reappearing, etc.
Please give this bug appropriately high priority, because it prevents
servers from coming up after power failures.
