I donnot see any problem in the messages, but just additional messages
related to negotiations occuring between host and targets.
The driver has been updated in -ac9 with the Ultra-160 (SYM53C1010)
support. This enhancement has been added by Pamela Delaney from LSILOGIC
and she probably wants these additional messages to be printed out to help
diagnosing real problems if any.
These debugging informations will obviously be conditionned soon a not be
printed out by default as in previous driver versions.
If you really want these messages to go away:

Both. :-)
You donnot want to read configuration space beyong byte 128 for chip
earlier than SYM53C896.
