Network Issue

Hello,

I am working on Linux 3.2.0.

We had a requirement to make Linux Real Time so using RT-PREEMPT
(patch-3.2-rt10.patch.bz2)

We are facing a network hang issue while running the periodic task of 5 ms.

cannot ping any more when task is running is ran for some time.

I am using Timer fd protocol to achieve this.

I would like to know if there is such know issue in this patch.

Any help will be appreciated.
