I see this periodically when a phy goes out to lunch on my system ... with me, it always seems to be phy0 of a port containing phy0-4 ... so phy1-3 still function to get messages. Can you try sending a link reset to phy3? It should be something like echo 1 > /sys/class/sas_phy/phy-X:3/link_reset and see if it just produces aic94xx: scb:0x80 timed out Again?
