Hi,
is it possible to disable the built-in 8250 driver of the recent (11.2) kernels from the boot command line?
Reason: I need to use a specific serial I/O board (Meilhaus ME 9100) that requires a patched 8250.c file to work (see http://www.meilhaus.de/fileadmin/upload/download/products/serial/me9x00-2.0.... for the patch, and http://www.spinics.net/lists/linux-serial/msg01650.html for a short discussion on the LKML).
As the de-facto serial kernel maintainer now, I'd be glad to accept this patch if it is fixed up as per the review comments in that thread.
If that happens, then you would not need to worry about this type of issue.
Unfortunately, I am just a user of this card. I just found this message while searching for a solution for this Mailhaus card.
Also, if you are having to patch the file anyway, you are building your own kernels, right? Then you shouldn't have to worry about building the driver into the kernel, right?
The idea is that I disable this (builtin) driver at boot time and use the patched driver as a module. This would allow me to use the original kernel and thus avoids the need to re-compile the whole kernel myself on every kernel update.
