Apparently this commit changed suspend procedure on mac80211, but it's
not obvious for me why it hangs :-(
Hangs are hard :-) It just sits there with a black screen and a white
cursor in the top left corner...
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 ?
Yes, I am using NM under KDE, with KDE triggered suspend. No wowlan
AFAIK. The last thing I see in the log is something from NetworkManager
that sees the device switching off. I can try again tonight and give you
the exact message.
I will also try without NM and bare wpa_supplicant and a plain suspend
through sysfs.
Any debug options you want me to enable? Netconsole won't work however...
Can you get more debug info if you try (as root/sudo -i):
echo devices > /sys/power/pm_test
echo mem > /sys/power state
