Hello Yinghai,

This looks more promising!

That seems to be the case yes:

[ 106.661152] PM: ... nb fw_pm_notify+0x0/0x150 done
[ 106.665939] PM: calling nb bsp_pm_callback+0x0/0x50
[ 106.670814] PM: ... nb bsp_pm_callback+0x0/0x50 done
[ 106.675775] pm_restore_console() before move

Then nothing, during the third resume.

http://gaast.net/~wilmer/.lkml/bad3.17-patched-console-restore.txt has
the full log.

(Some of your other debug lines in your patch don't seem to be logging
anything during my repro BTW.)
