Hello!

I've changed GPU from a geforce to radeon HD7770 few days ago and since then I get always computation errors on GPU WUs. Stderr output from task says:

(...)
[Sep 18 15:44:40 UTC] 1 cruncher has been started.
[Sep 18 15:44:40 UTC] Core compilation failed. Exiting.
[Sep 18 15:44:40 UTC] Core compilation failed. Exiting.
[Sep 18 15:44:41 UTC] *Break* Shutting down...
[Sep 18 15:44:41 UTC] Core compilation failed. Exiting.
(...)

(full output: http://moowrap.net/result.php?resultid=15338589)

The cruncher is restarted 10 times and every time it fails.

What may be the cause of those errors? I run other boinc projects which use GPU (Collatz, Milky Way) and they compute correctly.
My video driver is catalyst 12.6. I use 64bit linux.

Or maybe it is an upstream problem with dnetc?

EDIT:
it is an upstream problem with radeons 7xxx: http://bugs.distributed.net/show_bug.cgi?id=4471

Yep, Radeon 7xxx need the upcoming OpenCL D.net client to work since AMD decided to drop support for native Stream client. :( Upstream has a pre-release beta OpenCL client out so they are making nice progress on that front, though.
