I will be throwing a few GPU on this race to help out. Wish I was better setup but throwing GPU in last minute to assist. I hope this helps gain a spot or two.

I haven't had any luck getting valid work units with linux mint. This is really limiting the help I can give on this one.

[Dirk Broer]

I recognize your problem. I used to be able to score pretty good on MilkyWay with my HD 4770, until Windoze stopped supporting OpenCL 1.1
I eventually used my HD 7790 under Xubuntu Linux but -after an initial good start- all subsequent WUs errored out.
My Mint box does not have MilkyWay capable GPUs (Double Precision is required for MilkyWay).

[Jason1478963]

It appeared to be working until I looked at result status. I have 7870s and 5850s and a 5870 I believe that are double precision. I'm not sure what else changed that these no longer work in linux.

Same with my 7790. Used to work under Linux, until a month or two ago...

[Jason1478963]

Is it do to a linux update or a Milkyway update that caused the issue?

[Dirk Broer]

My guess is MilkyWay.
As Ubuntu 16.04 is a disaster, crunching-wise, on pre-OpenCL 1.2 hardware, my HD 7790 runs on a Xubuntu 15.04 box -in order to make maximal use of all GPUs in the system-, but lately it can't run MilkyWay anymore.

[Jason1478963]

It sure is frustrating to keep these cards working right under Linux as I haven't run them on Linux since poem. I'm not interested in windows 10 and keeping windows from breaking the drivers either. If the projects are trying to move to the latest and greatest all the time I may be done running GPU as its to expensive and to much work to keep upgrading and fixing.

I haven't been able to crunch any Milkyway tasks on my Radeons for a while now. Never did find out why.
