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

Kernel config
Config which worked with 4.4, processed by 'make oldconfig'.
Can you bisect? sorry i cant, i dont have the resources :( maybe eugene? commit f95429eccc570dc45d589c327bfcfddcdc3e8228. Reverting that makes suspend work with 4.5.0. This is a duplicate of bug 112781. Indeed, mine is Clevo P177SM fixed for me with 4.6.0 rc1 |
