SRU Justification

Impact:
Ubuntu 12.04.2 causes the system to be hung after running command udevadm info --attribute-walk --path=/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/ata1/ata_port/ata1 | sed -n 's/ ATTR{\(.*\)}=="\(.*\)"/A: \1=\2/p'
for sata controller. Sata controller in question is Marvel 9125

Issue can be reproduce by running checkbox certification on Atom cartridge with MArvell sata controller.
There is patch provided by MArvell and submitted upstream but not yet accepted.
