amd radeon vce init Error

I have a Dell inspiron 7548: configuration

I am using Fedora 23 (I shall upgrade to 24 whenever it gets released) and Win10 (only for MS Office and my Advisor)

I doubt if my AMD GPU (radeon r7 M265) even works in fc23. I faced problems while upgrading from Win8.1 to Win10. (Win10 upgrade provided M270 drivers instead of M265, So I had to disable, replace drivers and enable the GPU again)

NB1. I have another intel integrated graphics card that seems to work. Intel® HD Graphics 5500 (Broadwell GT2)

I receive the following error at system boot:

[16709.114481] radeon 0000:08:00.0: VCE init error (-110). [copied from dmesg]

NB2: I have to boot computer in fc23 + debug mode. Without the debug mode, boot routine hangs after changing root.

NB3: I am a grad student in Molecular Biology and know a little of python and bash programming necessary for bioinformatics. NOT a computer expert.

Thanks

Since you have two an Intel video card working and the Radeon card, what you need to do is:

lsmod |grep radeon

To check if radeon module is load and set it on a module blacklist that way it will not be load at start and will load only the Intel kernel module. To do this you must add a file in /etc/modprobe.d/ lets call it blacklist.conf the content of the file will be

blacklist radeon

Good luck

Thanks for the suggestions!

1) lsmod output:

radeon 1519616 1 i2c_algo_bit 16384 2 i915,radeon ttm 94208 1 radeon drm_kms_helper 126976 2 i915,radeon drm 344064 12 ttm,i915,drm_kms_helper,radeon

I frankly don't understand what the output means.

2) Tried blacklisting radeon as directed. But it does not help solve boot-hang. Still booting from + debug mode.

It means radeon kernel module is loaded and other modules depend on it. As you can see you also have i915 module loaded that is an Intel video module. Did you verify with lsmod that no radeon module is loaded after you did the blacklist?

Following is how the blacklist file looks like.

pradyumna@fc23 ~ 09:27:56 -> cat /etc/modprobe.d/blacklist.conf

blacklist radeon

The lsmod |grep "radeon" output is still unchanged. :-(
