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
