I cannot verify this problem.

This is really not needed.

We have tested the normal uart driver in a setup running on 5  serial
ports  (2  x  SMC, 3 x SCC, with Ethernet of the 4th SCC). No serious
load tests so  far,  but  basic  I/O  functions  worked  without  any
problems.

Ummm... AFAIK QSLinux is based on a 2.2.5  kernel?  That's  _awfully_
old.  I  can  imagine  that there were lots of problems with the uart
driver at this time. And other bugs as well.
