You can't signal out of descriptors and stop the queue after the

This reminds me an idea I had about MQ/MQPRIO qdisc

Suggested fix : add a TCQ_F_MQSLAVE flag to allow dequeue_skb() to test

Here PC is at __alloc_skb and shinfo-dataref is unaligned because
skb-end can be unaligned without this patch.

There is a problem with your kmalloc() or alignments on your architecture.
What is the SMP_CACHE_BYTES value ?
kmalloc() behavior doesn't have anything to do

The issue is calculation of skb-end, which is based upon calculated
'size' variable.
skb-end determines alignment of skb_shared_info, which is where the
alignment problem is occuring for Tony.

By increasing the allocation length of our rx skbuff the corruption issue is
fixed... I have increased it by 2... Were we writing outside our boundaries
of skb data?
Please let me know about this approach...
