Actually, I don't think the problem is gone, it's just gone into hiding
again.  What seems to happen is that as we alter code in scsi_lib.c,
particularly along the completion paths, it reappears and then
disappears again.  It looks like some obscure timing related bug,
possibly in the aic7xxx driver, or possibly in the mid-layer 

I've rebuilt my main SCSI test box to be aic7xxx based to see if we can
somehow find it again and debug it.

So, I'd like this bug left open against SCSI please, but you can
probably remove it as a current regression (I think it's probably been
hiding for a very long time).
