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.
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 ?
Created attachment 128910 [details] 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
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/)
