Comment 244 for bug 263555

Yes it is based on 2.6.27-rc6 and we have no idea how the system get in this state, but we got multiple reports now :-(, all the same, installing Beta1 with an e1000e card (I will collect PCI ids of all reports later) and during the first driver load you see:

e1000e: Intel(R) PRO/1000 Network Driver - 0.3.3.3-k2
e1000e: Copyright (c) 1999-2008 Intel Corporation.
e1000e 0000:00:19.0: PCI INT A -> GSI 20 (level, low) -> IRQ 20
e1000e 0000:00:19.0: setting latency timer to 64
input: PC Speaker as /devices/platform/pcspkr/input/input3
0000:00:19.0: 0000:00:19.0: The NVM Checksum Is Not Valid
e1000e 0000:00:19.0: PCI INT A disabled
e1000e: probe of 0000:00:19.0 failed with error -5

in the dmesg output (for more details see attachment #1 for the full log)
If you then try to boot into a other OS version (which was working before) the network card does not work anymore with the same error, which let me think that
the eeprom was overwritten or deleted and later I found the commit in later kernels for e1000 (comment #7) which sounds somehow related for me.

Our e1000e driver differs from mainline in 3 additional patches requested by
