Re: [BProc] Kernel: compile network devices as modules?

[Jeremy A. <arc...@co...>]

I understand about the advantages of kernel modules, but my question 
really is: "Do the network devices HAVE to be compiled as modules?"

For right now I have two computers with identical configurations. One 
is running the kernel that I compiled and has bproc running. The second 
computer is giving problems with the IRQ trap. To decrease the size of 
the kernel, I removed sound, usb, power management, and some other 
devices. Since the kernel is running on the first computer, I assume 
(my last words) that it will run on the second computer.

If anyone has successfully got bproc/beoboot working where the network 
devices are compiled into the kernel, I would be greatful if you just 
said so, so that I know that the problem lies elsewhere. None-the-less, 
tomorrow I will be recompiling the kernel (again) but this time with 
the devices loaded as modules.

Thanks for all your help thus far. The eventual cluster will have 240 
cpus in a single rack, and the single system image and netbooting will 
be very (understatement) handy. If the blades support PXE, I will try 
that too.

Thanks again.

p.s. If you work at LANL, send me an email, because I am sure I could 
use some pointers on this.
