Intermittant serial port failure

Hi All,

I'm trying to solve an intermittant serial port problem on an embedded medical monitor. We have determined that the port is receiving characters from the external device but the serial thread is not transferring the chars from the buffer. Has anyone seen this before? Looking for some guidance on what to look for. this problem happens at start up about 1 in 50 boots. We're using kernal 2.6.29.6.
Thanks!

With no information about the hardware, the software or the external device it is difficult to provide any sort of guidance. The first step is to contact the manufacture of the equipment and see if they are aware of the problem. Does this happen with all these type monitors assuming you have more then one?
