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). Two were u-boot and one was a proprietary boot rom.
So, the "problem" seems to be related to something unique with your
system.

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.
Thanks.
