Bug#346161: linux-source-2.6.15: serial card (fourport) stopped working

[Andreas Degert <ad@papyrus-gmbh.de>]

Package: linux-source-2.6.15
Severity: wishlist

I have a fourport serial card, it is correctly detected and configured
with the kernel from package linux-image-2.6.12-1-686-smp. The
detected ports are ttyS4 - ttyS7 (ttyS0/1 is standard serial ports,
ttyS2/3 not assigned).

With 2.6.15 it works if the (max) number of serial ports is changed
from 4 to 8 in the kernel configuration:

CONFIG_SERIAL_8250_NR_UARTS=8

I don't know if this change in behaviour was intended (2.6.12 works
with my card when this parameter set to it's default value of 4,
2.6.14 and 2.6.15 don't).
