Description KiR 2005-01-04 01:05:31 UTC

In gentoo-sources-2.4.26-r14 serial interface works only at 9600 bps.

Reproducible: Always
Steps to Reproduce:
1. compile gentoo-sources-2.4.26-r14
2. boot with this kernel


Actual Results:  
/dev/ttyS0 works only 9600 bps, however setserial -a /dev/ttyS0 report 115200 bps.
It seems drivers/char/setserial.c has a bug? because i replace all 9600 to 57600
and my modem works as expected. In version gentoo-sources-2.4.26-r9 and below
serial interface works ok.

Expected Results:  
Work at full speed.
