This bug does not only occurs in Kubuntu but Ubuntu 32 and 64 bits editions are affected as well:
I can confirm the bug during the boot process of the live CD of both Ubuntu 32 and Ubuntu 64
the last lines of the boot log are
8139cp 10/100 PCI Ethernet driver V1.2(MAr 22, 2004) 8139cp PCI dev 0000:03:04.0 (id 10ec:8139 rev10) is not an 8139c+ compatible chip 8139cp Try the 8139too driver instead 8139too fast Ethernet driver 0.9.27 ACPI interrupt 0000:03:04.0[A] GSI 16 (level, low) -> IRQ 177 eth0:Realtek RTL8139 at 0xffffc200|00 b.c00 00:40:45:2c:85:c0, IRQ 177
after showing the last line the system freeze and you need to apply a reset.
This particular PC is a laptop Philips X56 - Core 2 Duo T5600 - 1 GB RAM, - 80 GB hard drive - ethernet device Realtek RTL8139/810x - Wireless adapter Intel PRO/Wireless 3945ABG - Display adapter Intel 945GM.
The problem has also been reported at the Ubuntuforums in the same Laptop model:
http://ubuntuforums.org/showthread.php?t=292408&highlight=Philips+x56
and also a solution was posted, but requires the Instalation of Ubuntu Breeze and a Kernel recompilation,

however not all the user (including me) do have an available copy of Breeze.
