We encounted gpu hang on
hi,
I had the same problem with the same GPU this morning. the problem start after a loop of more than 20 kernel using host prt pointer of (256*47*sizeof(cl_int4).
first error was on enqueuemapbuffer -14 and on the next image processed error -36.
using uchar4 and ushort4 do not give any trouble even with a loop of 35 kernel.
Even with (256*55*sizeof(cl_ushort4) and a loop of 53 kernel everythings work.
