Again, even if you don't use the upstream kernel for production, I
suggest you

Hi Or,
I managed to update the kernel to OFED 3.0 to verify the bug, but I
can still produce the bug, maybe there're still some synchronice_irq

Hi Or,
We're testing our rdma kernel module, the tests is load module, create

I did some debug with gdb:
