[Bug 942106] Re: software raid doesn't assemble before mount on boot

[Jean-Philippe Guérard]

I believe that any disk listed on the fstab failing to mount will lead
to the dreaded initramfs console.


** Description changed:

- Booting from a software raid device can randomly or systematically fail.
+ Booting a system with a software raid device can randomly or systematically
+ fail.
  
  The system boot will fail at the initramfs stage and the system complain
- that it can't find the root device.
+ that it can't find the software raid device.
  
  The user ends up on the initramfs console. Rebooting might solve the issue
  (or not).

  Happens at once on boot.
  
  I happened to use the kernel 3.0.0-17, because the computer would not boot because of the bug that the line
  udevadm settle
  is missing in function degraded_arrays() in the file /usr/share/initramfs-tools/scripts/mdadm-functions which results in a halt on an initram fs console.
