Comment 2 for bug 48456

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:

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.
