Sorry for my belated response, but this usually happens when you access an aic chipset too soon after a chip reset. Try putting a delay before whatever access is causing this to see if it make s difference. Common problems include after a chip reset, touching any register will cause the card to reset, etc. -- Doug Ledford <[email protected]> GPG KeyID: CFBFF194 http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband
