I did that, but there are quite some assumptions implied by this 
approach, mostly that a file of that particular name is *required* for 
nay OpenCL implementation with this hardware -- and that is something I 
hesitated to believe in :-)

Always this same typo of mine   ^
This is either the reason for, or the result of, me not liking Ubuntu ;-)

Well, I did some of that cleanup (essentially it was removing the 
relevant mesa packages, purging the configuration (removing the entries 
in the /etc/OpenCL/vendors directory) and leaving the one from the AMD 
packages behind.

The results were most exciting:
- clinfo had no error messages any more
- I could start OpenCL Primegrid tasks via boinc

Definitely a step forward.

Unfortunately there are more steps ahead, as any Primegrid task using 
the GPU fails with an error:

opencl error: CL_OUT_OF_HOST_MEMORY

As I have no other real OpenCL workload I can try with any reliability, 
and I also have lots of host memory available, I suspect this due to the 
messy state of the software or its installation. And, as the 
installation has definitely not been done in any documented manner, I 
would not be surprised if that's the problem.

So, the challenge remains to find a way that reliably provides a working 
system, but it seems as though Mesa is not going to be the way towards 
this solution.

Thanks for all your input so far!

Arno
