e1000 driver in Kernel 2.6.27-4 not working

[William Marques]

When upgrading from kernel 2.6.27-3 to kernel 2.6.27-4 my ethernet NIC stop working.
No changes made, in any configuration.

Follows My Hardware:
Notebook toshiba Tecra A8
CPU Genuine Intel(R) CPU T2300 @ 1.66GHz
2.5 GB RAM
60 GB HD

Ethernet Card:

If I remove the line of the card in /etc/udev/rules.d/70-persistent-net.rules and boot with kernel 2.6.27-4, nothing happens, it's like the card does not exist.
If I modprobe e1000, and try to bring up manually eth0:

eth0: error fetching interface information: Device not found
If I boot back in kernel 2.6.27-3, everything works fine, /etc/udev/rules.d/70-persistent-net.rules is correctly configured, and so on.

I'm sorry, but this has nothing to do with Launchpad as a software.
Please file a bug against the kernel package in the Ubuntu project.
