Date: Fri, 08 Aug 2008 11:47:51 +0100 From: David Vrabel <david.vrabel@....com> To: Kernel development list <linux-kernel@...r.kernel.org> CC: e1000-devel@...ts.sourceforge.net, jeffrey.t.kirsher@...el.com Subject: e1000e: 2.6.27-rc1 corrupts EEPROM/NVM Hi, 2.6.27-rc1 kernels appear to corrupt the EEPROM/NVM of the 8086:294c ethernet device (ICH9 I think). After hacking the driver to ignore the bad CRC and MAC address I could view the EEPROM with ethtool and it was all 0xff. Testing EEPROM reads and writes with ethtool appeared to work but after a reboot of the system the ethernet device (see lspci -v output) was no longer present. Could invalid EEPROM contents with a valid CRC (as would be the case after my read/write tests) result in the device failing to enumerate on the PCIe bus?
