Description Paulo Dias 2016-03-22 22:53:33 UTC
the title says it all, the radeon module is making suspend hang. suspend never awaks, needs a power reset.

i enabled pm_test:

echo freezer
echo freezer > /sys/power/pm_test
echo devices
echo devices > /sys/power/pm_test
echo platform
echo platform > /sys/power/pm_test
echo processors
echo processors > /sys/power/pm_test
echo core
echo core > /sys/power/pm_test
echo none
echo none > /sys/power/pm_test
sleep 1
echo dmesg output
dmesg > /home/groo/dmesg.txt
sleep 1
echo running suspend
sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"

and the suspend never returns.

when taking a loot at dmesg_01.txt i get:

[    2.310584] pci 0000:03:00.0: hash matches

which is the radeon hw:

03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus PRO [Radeon HD 8850M / R9 M265X] (rev ff) 

so, i went to a tty, disabled X and removed the radeon module, and sure enough, suspend and resume worked. so right after that i reloaded the radeon module, tried suspend again, and again it crashed.

relevant dmesg below.

im using kernel 4.5.0 from ubuntu mainline
this also happens with 4.4.0 from xenial.

Blacklisting radeon makes suspend work. I use custom build kernel in Gentoo. For me this is a regression from 4.4, where the same config worked. Additionally (might be related?) in 4.5 external radeon card does not switch off automatically when not used, I have now to
echo 'auto' > '/sys/bus/pci/devices/0000:01:00.0/power/control'
to turn it off.
BTW, When it is turned off, lspci shows:
# lspci -s 01:00 -v

Comment 2 Eugene Shalygin 2016-03-23 10:16:07 UTC
Created attachment 210331 [details]
Kernel config

Config which worked with 4.4, processed by 'make oldconfig'.
Comment 3 Alex Deucher 2016-03-23 13:52:04 UTC
Can you bisect?
Comment 4 Paulo Dias 2016-03-24 19:47:03 UTC
sorry i cant, i dont have the resources :( maybe eugene?
Comment 5 Eugene Shalygin 2016-03-25 15:59:47 UTC
commit f95429eccc570dc45d589c327bfcfddcdc3e8228. Reverting that makes suspend work with 4.5.0.
Comment 6 Alex Deucher 2016-03-25 16:05:37 UTC
This is a duplicate of bug 112781.
Comment 7 Eugene Shalygin 2016-03-25 16:13:46 UTC
Indeed, mine is Clevo P177SM
Comment 8 Paulo Dias 2016-03-27 01:25:39 UTC
fixed for me with 4.6.0 rc1
