Bug#549535: Same on sparc

[Jochen Friedrich]

Hi,

the same happens to me on sparc hardware. This is the log i get from the 
serial port:

------------------------------------8<------------------------------------

Gave up waiting for root device.  Common problems:
  - Boot args (cat /proc/cmdline)
    - Check rootdelay= (did the system wait long enough?)
    - Check root= (did the system wait for the right device?)
  - Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/md1 does not exist. Dropping to a shell!


BusyBox v1.14.2 (Debian 1:1.14.2-2) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
------------------------------------8<------------------------------------

If i now manually execute /scripts/local-top/mdadm, the boot process 
continues.

So it looks like the problem is some missing synchronisation between 
udev and mdadm.

Thanks,
Jochen
