--- Bob Liu 2012-08-22 05:18:28

disable CONFIG_PM_RUNTIME can fix this issue.

--- Vivi Li 2012-08-24 03:56:17

It seems not problem of CONFIG_PM_RUNTIME.

CONFIG_PM_RUNTIME is still enabled in this test, but due to some commit between

kernel commit a1810c5b9efd3d0806ae6d89f26e534e313c3e1a and

88c728083aa506b169d8f7308c568cb3544873f7, this case pass.
