gpu hardware vm is enabled yosemite 10.10.5

[psyzerg]

Hi I installed yosemite 10.10.5 and when I connect my external graphic card ATI Radeon 7770, I am not able to boot it stuck on panic error: "gpu hardware vm is enabled"

I am only able to boot with -x

I tried to change AMDRadeonX4000.kext. with this values and this worked in past on 10.10.3 or 10.10.4 can't remember exact version...

<dict>
<key>CAIL_DisableDrmdmaPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableDynamicGfxMGPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableGfxCGPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableGmcPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableStaticGfxMGPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableUVDPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableVCEPowerGating</key>
<integer>0</integer>
</dict>

But this is not working anymore, can anyone help me?

Apparently problem was in AMD7000Controller.kext and not in AMDRadeonX4000.kext as I thought at first.

So I reverted back AMDRadeonX4000.kext to original system version, rebuild permissions and cache with kext wizard,

after that installed AMD7000Controller.kext

rebuild permissions and cache with kext wizard and now I have fully working Radeon 7770 graphics on my yosemite 10.10.5 ! yeeey
