this is related with the commit: commit 77437fd4e61f87cc94d9314baa5cbf50e3ccdf54 Author: David Brownell <dbrownell@users.sourceforge.net> Date: Wed Jul 23 21:28:33 2008 -0700
probobly it's depend on this message: [ 173.076075] ata1: link is slow to respond, please be patient (ready=0)
so it's looks normal for this board and harddrive. I think it should be some way to change default TEST_SUSPEND_SECONDS by .config or kernel-parameter. I changed default settings to 10 in kernel/power/suspend_test.c but this is not the way it should be done.
