This is not a real patch but it works fine for me:

+++ drivers/char/serial.c Thu May 3 09:29:34 2001

serial_outp(info, UART_LCR, 0xBF);
This stuff got changed between 2.4.3 and 2.4.4 but I don't know why and
it broke my serial console. Please let me know when you know the "real"
fix for this problem.
