This usually tells us somebody trod on the adapter's data areas.

Frequency errors indicate the ring clock and the adapter clock
differ. Maybe a cabling or an electromagnetic interference
problem. The line error indicates a corrupt frame got put on the ring
at some time.

I don't have a reference handy to tell me what the ret_code 28 means,
but the xmit error D8 is meaningless in this instance and can be

Could either be a wonky adapter or a hardware conflict with another
adapter or ? I won't be able to find out what the ret_code 28 means
until I can look at the adapter reference tonight.
