I just built an 8250. 8260, and 8270 from a very recent 2.6 tree today and they all worked fine. They all had different serial port configurations (SMC1, SCC1 and SCC2).

This is code that has existed for many years in Linux and appears to continue to work fine. We need to identify what is causing the problem in your environment, not look for some hack around it.
