Synopsis: [ed][panic][patch] large traffic yields occasional panics State-Changed-From-To: open->feedback State-Changed-By: yongari State-Changed-When: Tue Nov 29 23:01:36 UTC 2011 State-Changed-Why: It seems that the code path referenced invalid address when a mbuf length is odd bytes. I created a new diff based on your patch since your patch may still invoke bus_space_write_1(9) if mbuf length is even bytes. I also added mbuf length check and used NULL in comparing a mbuf pointer. You can find the patch at the following URL. http://people.freebsd.org/~yongari/ed.pf.diff Let me know whether this patch works for you.
