Something wrong with radeon. How to turn them off tatally ?

Hello guys, i have a dell laptop with hybrid vga. But i use only integrated graphics. So, i blacklisted radeon some times ago and used vgaswitcheroo to turn them off.
But a couple of days ago radeon card was alive, again, but i have no idea why.
for example "cat /sys/kernel/debug/vgaswitcheroo/switch" produces:

0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynOff:0000:03:00.0  #Is DynOff == Off ? 

i see radeon in output of "sensors":

radeon-pci-0300
Adapter: PCI adapter
temp1:            N/A  (crit = +120.0°C, hyst = +90.0°C)

lspci | grep VGA produces:

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus PRO [Radeon HD 8850M / R9 M265X] (rev ff)

lsmod | grep radeon

ps -I won't totally turn them off.
pps - I already tried acpi_call, but test.sh doesn't found signal for my card. i guess.

Sorry for my bad english and i thank you !

Re: Something wrong with radeon. How to turn them off tatally ?

The discrete gpu should be totally off. Those dmesg messages are normal, they are printed when the driver loads and when X starts, but when the card is not in use the driver will automatically turn it off.
