Greetings.

I have an Asus A7N266-VM motherboard, which uses the nForce-220D chipset. 
I'm using RedHat 8.0, but I don't think the problem is RedHat specific.

Description of the problem:

Whenever I start my computer with USB devices connected, the computer will 
hang right after loading module usb-ohci. The hanging also occurs if I 
start the computer without USB devices, and then hot-plug those. There is 
no kernel panic nor any error messages (on console), everything just 
stops. However, sometimes everything may go fine, if I have just ONE 
device (printer) connected, and I don't try to hot-plug it.

This happens with both RedHat kernels (eg. 2.4.18-26.8.0), and a
vanilla 2.4.20 (compiled with the same config as the RedHat default 
kernel).

I also have a solution. If I compile the kernel (whichever version of the 
two) with the same config, but *excluding* APM support, everything works 
just great. Loading APM module with USB devices connected results in a
similar hang as described above.

So, there seems to be some serious conflict between the USB driver and the
APM driver. I don't really know if this more of a USB or APM related
problem, and therefore I'm not very sure to whom a bug report should be 
sent to.

I'd like to hear your views and opinions about this whole thing.
