求助：ultra10的asy1:silo overflow 问题

njdexp

ultra10的机器，启动进入CDE后，过几分钟跳出来，出现：
NOTICE：asy1:silo overflow
NOTICE：asy0:silo overflow
NOTICE：asy1:ring buffer overflow
的错误信息，然后进入到OK状态。
想请教一下，是不是主板有问题了？
谢谢回答！

A "silo overflow" happens when input to a serial line comes in faster   than the computer can process it.


The "silo" referred to is a hardware input buffer associated with a serial port. The serial line hardware (e.g., ALM board) detects when the buffer overflows and sets a bit in a status register to warn the  computer that some incoming data was lost on a given line.

那就是主板上有部件有问题？
