udevadm info --attribute-walk command hangs on Marvel 9125 controller

[Narinder Gupta]

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.
Here are the discussions happened so far.

 http://www.spinics.net/lists/linux-pci/msg20596.html

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

Test Case:
See above.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
