[Bug 942106] Re: mdadm-functions missing udevadm settle (?)

[Jean-Philippe Guérard]

I was able to test this patch using the following method: I added a
printed line before and after the "wait_for_udev" command. I then
rebooted a number of times and verified that the first line appeared
from time to time before all MD device were assembled and that the last
line always appeared after all MD device were assembled.

Title:
  mdadm-functions missing udevadm settle (?)

Status in “mdadm” package in Ubuntu:
  Confirmed
Status in “update-manager” package in Ubuntu:
  Fix Released

Bug description:
  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.
