[ofa-general] Re: [PATCH 4/4] [RFC] IPoIB/cm: Add connected mode support for devices without SRQs

[Pradeep Satyanarayana]

With these set of patches applied I see some random crashes and they
all have one characteristic -they are associated with an skb. I am
running netperf tests and most times see a crash. However, a few runs 
have also completed successfully.

The tests were run on IBM HCA on ppc64 machines.

Most often I see panics in either ipoib_cm_handle_tx_wc() when 
dev_kfree_skb_any() is called or in ipoib_cm_handle_rx_wc() when some
skb operation is being performed.

This appears to be a race wherein a freed (and maybe reused) skb is 
being accessed.

I have not yet been able to put my finger on the offending code
fragment. Continuing to investigate.
