Case 7 ...FAIL
POWER AD73311 TEST (SUSPEND-TO-RAM) FAIL
Follow-ups
--- Bob Liu 2010-09-13 05:40:16
The bug is like "[#6248] test fail on bf537-stamp with suspend to ram mode
in ad1836 power testing".
And I also can't repeat it.
But now ad73311 driver don't support suspend/resume.
After resume there will be no sound neither capture nor playback.
