Two problems after changing the kernel

[colt]

I recently compiled and installed a kernel 2.6.36 in the place of an older kernel, but one of the two problems that came up was that during the boot process a message similar to

fs Usbdevfs cannot be mounted

shows up.

I guess that means that no usb device should be working in the newer kernel, however I am here writing this using my usb keyboard and my usb mouse, so what that could mean?

The other is this message:

Applying iptables firewall rules: iptables-restore: line 20 failed"

that comes up during the boot or when I try to start the service through

sbin/service iptables --full-restart

That happens only with the new kernel 2.6.36.3 that I recently compiled and installed.

So I searched for files with

find / -name *iptables*

and the only thing that came were the initialization scripts from rc2.d to rc5.d.

I then gave a look into rc5.d and the 20th line was a blank line.

So were I should look for the 20th line? Or anything else that I can do localize the problem?

Thanks for the help
