I have gather the file you recommend + clinfo.log

When i use clinfo after installing the driver 18.30 it report an error.
I have also installed codexl and when i ask information, it give no result in
the tab 'opencl devices'.
You can look at the end of the clinfo.log file.
I think that there is a problem when trying to access to the opencl device
properties.
