Is it convenient to attach your kernel, or send by email to debug?
It is a known issue (similar bugs https://bugs.freedesktop.org/show_bug.cgi?id=98704.
), but the workaround can't fix the your problem, so need the kernel to find out the root cause.
Comment 2 shiva 2017-01-10 06:52:02 UTC
i am using kernel v4.9 i.e  linux-headers-4.9.0-040900-generic_4.9.0-040900.201612111631  
from  http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9/

Same problem,

Ubuntu 16.10  (4.8.0-32-generic)
Graphics Intel HD 4400

OpenCL *is* working in general, but throws this assertion when running zogminer.

I'm a developer with some minor experience on WebKit - you want me to set up a debugger and try for a stacktrace and all ?

stack trace

Here;s just a quick stack trace.   if I get some time, I may step into
this code and perhaps lend a hand on a fix.   I'm new here so pardon (and inform)  me of any doofus breaches of protocol and procedure and such
Comment 5 Rebecca Palmer 2017-02-02 22:29:19 UTC
I suspect they meant kernel as in OpenCL source code, not kernel as in operating system.

If possible, also try the current development version (i.e. git clone https://anongit.freedesktop.org/git/beignet.git ; instructions at https://www.freedesktop.org/wiki/Software/Beignet/)
