Re: unresolved symbols still in 2.4.30-rc2 (usbserial needs symboltty_ldisc_ref and tty_ldisc_deref which are EXPORT_SYMBOL_GPL)

Thanks for suggestion - I hadn't noticed that it had slipped out of date.
I took your advice and upgraded to 2.4.27 and rebuild (from clean)
the kernel and modules again.

$ bash scripts/ver_linux
 ...
Linux dd 2.4.30-rc2 #2 Sat Mar 26 11:37:17 PST 2005 i686
 ...
modutils               2.4.27
 ...

I'm still getting unresolved symbol tty_ldisc_ref and tty_ldisc_deref

dd:linux# insmod usbserial
Using /lib/modules/2.4.30-rc2/kernel/drivers/usb/serial/usbserial.o
 ...: unresolved symbol tty_ldisc_ref
 ...: unresolved symbol tty_ldisc_deref

After changing CONFIG_USB, CONFIG_USB_UHCI, and CONFIG_USB_SERIAL
from modules (=m) to built-in (=y) and another clean rebuild
I am able to boot cleanly and load modules that depend on usbserial

I would really like to get usbserial to be a module again
without getting the "unresolved symbols" for 
tty_ldisc_ref and tty_ldisc_deref
