2.6.0-test5 vs. modem cards

2.6.0-test5 vs. modem cards

[Norman Diamond]

When inserting a modem card, 2.6.0-test5 continues to have problems which
earlier 2.6.0-test versions had, which can be solved by booting 2.4.19.

In file 8250_cs.c:
Line 61, identifies itself as "serial_cs.c" instead of "8250_cs.c".
Line 119 identifies itself as "serial_cs" instead of "8250_cs".
My partial understanding of Linux PCMCIA operations yields a guess that line
119 is part of the cause for failure during execution, whereas line 61 only
potentially confuses future maintainers.

Later in the same source file, calls to register_serial() and
unregister_serial() compile but fail during execution.  Of course in order
to make it execute in the first place I have to manually modprobe 8250_cs,
because of the reason mentioned above.  /var/log/messages gets reports that
those symbols are unknown.

Its going to get renamed back to serial_cs shortly.

I have no idea how you managed that.  The configuration subsystem does
not allow you to build 8250_cs.c as a module without building 8250.c in
some manner, and 8250.c provides those symbols.

OK.

I built 8250.c as a module, but might have neglected to modprobe it.  Since
a manual modprobe of 8250_cs also neglected to automatically modprobe its
dependency 8250, there might be breakage in modprobe, or this might just be
additional breakage in the naming of 8250 vs. serial.
