Hi,
The crashes were solved.
I added a delay at the exit routine, just prior to the thread stop, so that
the last __kfree_skb() called by net_tx-action
will take place prior to the thread stop
Thanks for everyone who tried to help.

A delay never solves a synchronization problems
It only delays (pun

And I have also allocated the skb, and free it from the thread itself -
that also worked fine

However, when i do the rmmod the machine crashes , i.e., performs a reset !!
When I remove the netif_rx the rmmod returns ok.
Your best bet to debug this is to connect a serial cable to the machine
and set the kernel such that it logs

1) - when there is such reset , is there antyhing written in the kernel
log ?
can you please

Chava, you mix thing up. There's no such thing as kernel context.
All kernel code is run either:
* In interrupt context.
* In process context.

I have build a kernel module that runs a kernel

-Fill the proper sk_buff fields

Have you skb_reserve()'ed headroom for all these headers?
Maybe

No. The typical case for network reception is alloc from interrupt
context (card irq handler), free from process context (at the
