Hi, I'm emailing you to report a bug with the serial driver in linux kernel 2.6.14.2, you are listed as the maintainer in the MAINTAINERS file, so if I've sent you this bug report in error please tell me where I should be sending it.

I'm using slackware 10.2 on a AMD K7 (XP 2600) this is a 32bit i386 compatible machine.

in 2.6.14.2's menuconfig, under Device Drivers->Character devices->Serial drivers if I select the option 8250/16550 and compatible serial support to be compiled into the kernel, it works fine. If I select it to compile as a module, the module 'serial' is not installed when I do make modules_install. I'm also pretty sure it's not being compiled at all when selected to be compiled as a module.

Just to be clear, the help for that option specifically says the module will be named 'serial' if the name's wrong, could you tell me what it is named?

I don't know what's wrong with it, nor where to check. Could you give me some pointers on what to check so I can give you more information? I really prefer to have as much as I can as modules as my computer has to boot using a floppy disk.

It's actually called '8250' and it depends on 'serial_core' as well. I'll fix the docs.

And note: you're on verizon - I suggest if you want to receive replies from me (in the vague hope that you'll read the linux-serial list archives) that you locate a different ISP, or alternatively use gmail etc.

(Someone else on the linux-serial list may like to forward this and my previous message to Timothy.)
