(see http://forums.fedoraforum.org/forum/showthread.php?t=133591&highlight=hangs)

So I found the problem why I didn't have the network and why It hung.
It was due to the sis190 nic installed.
I changed the MTU to 1480, and all worked
Until I started big lan transfers and the systems hangs :(
I now changed mtu to 1492 and this seems to be better.
But still I have a weird problem:

When turning on the system, it keeps hanging on the network start
unless I first boot into windows, reboot, start linux and then it works fine

Also whatever IRQ I set in the bios, it is still different in linux.
This is the ifconfig output

eth0 Link encap:Ethernet HWaddr 00:14:85:4C:FA:D2
