When I use my own kernel ( means that I configure and compile kernel my self ), I alwasy get bad messages. None of them dangerous. However, I am just unhappy read those message every time I boot into my machine. In my latest kernel, 2.6.2 I got these messages:

Mounting USB filesystem:
fgrep: /proc/bus/usb/drivers: No such file or directory

Initializing USB HID interface: /sbin/modprobe: unrecognized option '--first-time'
Usage: /sbin/modprobe [--verbose|--version|--config|--remove] filename options

FATAL : Error running install command for hid

Initializing USB keyboard: FATAL: Module keybdev not found [FAILED]
Initializing USB mouse : FATAL: Module mousedev not found [FAILED]

Yeah, I know I still can live with these messages. I can play 3d game. I can listened to the music. I can connect to internet. It just.................... annoying.....................

When I use the default kernel that comes from Fedora ( Yeah, I use Fedora Core 1 ), none of these messages exist. Or....... They are [OK] at all. As you can see I got two [FAILED] already.

So, how can I get rid of these annoying messages ????

Well, do you have a USB keyboard and mouse? If not then remove the support for them from the kernel. If you do, you could try building them as modules.
In fact since lots seemed to fail on USB. What USB devices do you have?

I got USB to PS/2 mouse and USB printer. What I don't understand is with default kernel, I got message like this:
Initializing USB HID interface [OK]
Initializing USB keyboard [OK]
Initializing USB mouse [OK]
So, I enabled USB support for mouse and keyboard in my new kernel. And I got the annoying messages. It keeps looking for mousedev and keybdev module and say " I can't find it!!!"

But that's not important anymore because my Fedora got trouble. Imagine the situation: You were browsing for sometimes. And for some reasons you want to boot into another kernel. Suddenly the Linux system didnt recognize my ethernet card then kudzu asked "do you want to remove the configuration for the ethernet card D-link blablabla???". I asked yes. Then I can not connect to internet. I tried all kernel I have in Fedora. All of them didnt recognize my ethernet card anymore. I couldn't live without internet. I checked in Windows and Knoppix 3.3. I could connect to internet with them.

I am in holiday now. So I think I better spend my time to migrate my desktop into Debian testing or unstable than track the problem in Fedora that can spend many hours!!!!!! It is tragedy........
