The errors you posted look very much like termination problems. The driver
could be munging the termination on your controller. Please try the pre15
patch I just put up and also read the README.aic7xxx file concerning the
aic7xxx=stpwlev and aic7xxx=term_override options. If the pre15 patch
doesn't solve your problem, then please try to make things work using those
two command options. There are descriptions in the README of how to use
them. At least that would confirm for me that the problem is termination
related.
