[Fog] FOG imaging on Samsung NC20's

[Tricks]

Hello all,

The last few weeks I've tinkering with a FOG server and it's gone well on the machines I've tested with. I've now got a set of 16 Samsung NC20's which I'd love to image with FOG but it's not working. With the FOG server set to upload an image, I PXE boot one and get as far as;

Loading fog/kernel/bzImage.................
Loading fog/images/init.gz...................
via_rng: cannot enable VIA C3 RNG, aborting
via_rng: RNG registering failed (-19)
sky2 0000:02:00.0: cannot assign irq 0

My linux knowledge is quite basic, any support would be appreicated.

Im not an expert on this, in fact im far from it, but i have managed to do a little research for you.

All i can seem to find is the IRQ error, is says cannot assign IRQ0 which is default for system timer.

Have you tried checking the sytem settings on the server and the imaging machine to check this? ensure the corrospond with each other perhaps.

Like i said, sorry if this is all false information, i personally dont know it that well.

Just thought it may be worth looking at.

The C3 RNG is the random number generator built into VIA's C3, and obviously carried forward into the Nano CPU. I cannot see how this would be relevant with PXE booting though. It may be a BIOS option you need to enable.

Thanks for the replies, unfortunately nothing really stands out in the BIOS.. pretty standard Phoenix BIOS setup. There are cpu power saving and memory power saving options which I've tried anyway but didn't help.

This problem is now solved, it was a bug that was fixed in the latest kernel. The tricky bit was knowing how to update the kernel since the autoupdate wouldn't work over our proxy/firewall and while you could do it manually the website didn't seem to explain how!

At some point FOG will be updated with the latest kernel but in the mean time, to fix the problem you just need to replace /tftpboot/fog/kernel/bzImage with latest kernel.
