kc705 Base TRD drivers in OS Linux (32/64bit) is not stable

Hello, i am used kc705 Base TRD project. All system (FPGA+driver+Host(Ubuntu)) is working (but short time - about 7-12 hours). 

I want to understand what was happening.

1) FPGA (NGC-core PCIe<->DMA from Norwest has limited period of time) ?

2) Linux driver (has limited period of time or somewhere BUG)? 

3) User APP is incompatible with OS Ubuntu (Fedora16/KUbuntu). For example, driver The driver is not correctly uses memory in the kernel driver?

4) Something else which I guess is not???

 

I've seen other similar post in forum, they did not help me.

 

Thank you.

Thank you. Your example TRD for card zc706 is working.

All started well, but it works for a limited time (11 hours 55 minutes). Next, the host freezes . It is impossible to keep track of which part is failing. Where to look for the problem? (OS, Linux or HW Design)?
