Does the patch below have any improvement?
I still get a clicking on the standby -> active transition with the patch provided on top of 4.1-rc4.
OK, just to be sure, could you check whether changing msleep(10) to msleep(100) makes no difference? Also put a line like pr_info("XXX power up %x\n", nid); after msleep() call to see which nodes are powered up dynamically.
Increasing the delay, if anything, makes the crackle when powering up seem a little longer. dmesg log looks like:
[ 4206.075557] XXX power up 2 [ 4206.179671] XXX power up 14 [ 4206.291758] XXX power up 3
