Error from aic7xxx

[tmuller at agora.rdrop.com]

Hi all,

Well, I've got some good news and some bad news.  The good news is that this
seems to have cleared up once I put the jumper on the "Disable Target Initiated
Syncronous/Wide Negotiation".  So now the bad news.  I still see one of 
these errors during bootup, but only one.  Now dmesg is:

Ok, what do you think?  Is it going to be safe to use?  I can't believe that
the messages are damaging since just by turning off the target negotiations
all but removed them.  Comments Doug? 

Btw, setting the tagged queuing to none does not make a different in the error
showing up.  I tried it via lilo and also by disabling it in the kernel build.  The same error shows up in both situations.
