Every time I format or write do floppy disk, my system hangs.

I know the problem is with an option in the Kernel. Because I recompiled
the kernel with the .config file of the Kurumim distribution and everything worked.
But with this configuration my network system became very slow ( I have no idea why) so I had to switch to the old kernel.

Someone knows what option is this?

Thanks guys.

what is your distributon?
Have you compiled your kernel by hand or are you using something generic?

My distribution is RedHat 9.0 and I m compiling kernel 2.6.7 from source downloaded from the linux kernel official site. The kernel of the Redhat is 2.4 with some patches of 2.5 (I dont know why?). With this kernel the flopyy doesn't work too. I migrate the .config file of the Redhat' s kernel to the kernel 2.6.7 using the command "make oldconfig" but the problem persist. T here are many options in the kernel that I don't know what it means. So I never change them. It's amazing how easily you can configure things wrong in the kernel. Sometimes I feel like a rat with god's power.

But this is where the fun is ........

well, knowing RH kernel, they probably enabled lot of options you dont need and your kernel is probably a modularized one ( mean you have most things in modules, not included, so you might have to _load_ the module in order to make it work).

make sure you have IDE/ATAPI Floppy option included, and turn off useless feature like ftape and parallel floppy drive. I guess these one could be the trouble... There is no magic, you will have to reconfigure your kernel again and again 'til you find the correct option.

My opinion is that you should just start back a kernel from nothing (keep a back up of the old one!!!). Of course, you will probably need a dozen of tries before you get everything working, but it's usually the best way to just avoid a buggy feature you couldn't find otherwise
