I made a really simple mistake. I have created a 16 byte buffer but transfered 24 bytes to FPGA global memory. This was crashing the PCIe. I have to restart the entire system because of this small er...

Are you sure the crash is happening because of the clEnqueueWriteBuffer() and not the FPGA reconfiguration? If you are using Arria 10, run-time reconfiguration has a relatively high chance of failure due to partial reconfiguration, especially on the older versions of Quartus. However, if you are sure your issue is caused by clEnqueueWriteBuffer() and you can reliably reproduce it, I recommend opening a ticket with Altera directly and reporting the issue.
