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.
