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
