I use official RHEL 7 driver as follows:

yum install fglrx64_p_i_c-15.302-1.x86_64_rhel7_64a.rpm

aticonfig --initial 



After reboot, CentOS (7.2) successfully restarted but failed on entering graphics mode.

check /usr/share/ati/fglrx-install.log, it said:

Unloading radeon module...

rmmod: ERROR: Module radeon is in use

Unloading drm module...

rmmod: ERROR: Module drm is in use by: ttm drm_kms_helper radeon

[Message] Kernel Module : Trying to install a precompiled kernel module.

[Message] Kernel Module : Precompiled kernel module version mismatched.

[Error] Kernel Module : Kernel module build environment not found - please consult readme.

[Reboot] Kernel Module : dracut

[Message] Driver : End of installation


I searched on google, found some a post said the error is related with Secure Boot. But I checked in BIOS, Secure Boot option already has been closed.

Can anyone give some suggestions?
