On Rev. B silicon, we disabled the enhanced busfree detection logic to
close holes in detecting busfrees that occur after a packetized target
transitions to a non-packetized phase. The most common case where this
occurs is when a target is externally reset so the controller believes
a packetzied negotiation agreement is still in effect. Unfortunately,
disabling this feature seems to cause problems for the 7901B. Re-enable
ehanced busfree detection for this part until I can get my hands on a
samble to figure out if the old workaround is necessary and, if so, how
to make it work correctly.
