A kernel with this these patches load the e1000e driver fine on a test machine which has a OK NVM checksum.
But it freeze on one machine which has a wrong checksum.
On this machine the NVM seems to be OK, but the NVM valid bit is cleared. If I would set this bit, the NVM checksum would be OK again. This is the T61 notebook which did show this error after openSUSE 11.1 Beta1 install after a reboot during X setup.
