SRU Justification

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.
Here are the discussions happened so far.


Canonical can fix in kernel once patch has been accepted upstream. Patch details are as follows

Test Case:
See above.
