Public bug reported: I've radon blacklisted through a conf file in modprobe.d directory Inside a X session I've modprobe radeon. No problem here Then I've echoed OFF to /sys/kernel/debug/vgaswitcheroo/switch. No problem here Radeon card was off according cat /sys/kernel/debug/vgaswitcheroo/switch and lspci | grep VGA (ff present for radeon). Also fan stopped a while after. Then I've suspended. Ok here. Resumed again with no problem. Then I've echoed OFF to /sys/kernel/debug/vgaswitcheroo/switch. No problem here BUT card seemed not being turned off. cat /sys/kernel/debug/vgaswitcheroo/switch showed the radeon as off, but lspci | grep VGA doesn't showed the ff at the end. So I tried to power ON the radeon card again (in order to turn it off then), and I've gotten the kernel "oops"
