Apparently this commit changed suspend procedure on mac80211, but it's not obvious for me why it hangs :-(
What is your user space configuration (are you using NM or other software or maybe just wpa_supplicant)? Are you using wowlan? If you do add no_console_suspend boot parameter does it print some diagnostic messages during suspend before the hang ?
Thanks Stanislaw
