clinfo hangs when using fglrx-core on Kaveri

0

I've had a working installation with OpenCL running and unfortunately executed dist-upgrade on my Ubuntu (because of the glibc bug). Then I recognized that OpenCL was not working anymore.I re-installed fglrx-core and tried to execute clinfo. Curiously, it runs endlessly with a CPU usage of 100%. Additionally, I cannot kill it with SIGKILL (kernel mode?).

Here is my system specification and some driver infos:

  • Kaveri [Radeon R7 Graphics] APU
  • Ubuntu 14.04 LTS (Linux ***** 3.13.0-77-generic #121-Ubuntu SMP Wed Jan 20 10:50:42 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux).
  • fglrx-core/trusty-updates,now 2:15.200-0ubuntu0.6 amd64 [installed]

I ran strace clinfo on the broken system and an equivalent one (same configuration, but still working). Here is the broken version and the working one.

Do you have any idea how to solve this problem?

In the broken version's strace, folder /etc/ati and various files inside that folder do not exist. clinfo is known to crash if /etc/ati is not present. You can try to copy folder /etc/ati from the working machine and see if that helps.

Thank you for your answer. As I did a fresh install of Ubuntu some months ago, I am unfortunately not able to check this answer to be correct and give you full credit. – fyaa – 2016-09-15T06:25:00.110
