Thanks, I still don't understand how it is that e1000e_recover didn't work for you, but I admit that I have been using it as a tool, and don't understand its inner workings.
Let's try another approach to get the invalid NVM content listed, this time by the driver when it reads the data. I attach a patch "e1000e-1.0.15.shownvm.patch" which can be applied our latest e1000e sourceforge release. To install the driver, and collect that result , please proceeed as follows 1) Copy this patch to a local directory 2) Download e1000e-1.0.15.tar.gz from http://sourceforge.net/projects/e1000/files/ 3) Untar the tarball to a local directory, tar xvzf e1000e-1.0.15.tar.gz 4) cd e1000e-1.0.15/src 5) Apply the patch patch -p2 <../../e1000e-1.0.15.shownvm.patch 6) Remove the old driver, build & install the new one rmmod e1000e make insmod e1000e.ko 7) The system message log should have the NVM content that was read. The driver should also load even in the presence of the errored NVM. Please let me know whether it does load and work, and .send me the dmesg log that includes the NVM dump, and I will see if I can fix it up and return it to you with instructions on how to apply the fixed-up version, Thanks Dave ________________________________________ From: boun...@canonical.com [boun...@canonical.com] On Behalf Of bonsiware [bonsiw...@gmail.com] Sent: Wednesday, October 07, 2009 10:28 AM To: Graham, David Subject: [Bug 263555] Re: [intrepid] 2.6.27 e1000e driver places Intel ICH8 and ICH9 gigE chipsets at risk lspci -tv: +-19.0 Intel Corporation 82566DC Gigabit Network Connection lspci -xxx: 00:19.0 Ethernet controller: Intel Corporation 82566DC Gigabit Network Connection (rev 03) 00: 86 80 4b 10 03 01 10 00 03 00 00 02 00 00 00 00 10: 00 00 40 fe 00 40 42 fe 21 18 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 86 80 00 00 30: 00 00 00 00 c8 00 00 00 00 00 00 00 0b 01 00 00 dmesg: [ 1.652371] e1000e: Intel(R) PRO/1000 Network Driver - 1.0.2-k2 [ 1.652374] e1000e: Copyright (c) 1999-2008 Intel Corporation.

This is limited to the new e1000e driver, and reports have only appeared from users of "82566 and 82567 based LAN parts (ich8 and ich9)" (to quote Intel). The reports seem to be isolated to laptops, but it is not clear if this is because desktop/server parts are not vulnerable, or if use cases simply increase the chances of laptop users being hit. Once this corruption has occurred, recovery may be possible via a BIOS update, but may well require replacement of the hardware. Use of Intel's IABUTIL.EXE is strongly discouraged, as it will worsen the problem to the point where the network part will no longer appear on the PCI bus. (this is a new description, the original one was based on too much guesswork. Below are the URLs originally referenced) (the driver i blacklisted in Ubuntu for 2.6.27-rc in the latest releases, so if your network is not working, it doesn't have to be damaged, but just disabled in order to prevent any accidents until this bug is solved, don't wary!) http://www.blahonga.org/~art/rant.html (search for "em0") http://www.mail-archive.com/e1000-de...@lists.sourceforge.net/msg00360.html http://www.mail-archive.com/e1000-de...@lists.sourceforge.net/msg00398.html ** Attachment added: "e1000e-1.0.15.shownvm.patch" http://launchpadlibrarian.net/33264068/e1000e-1.0.15.shownvm.patch -- [intrepid] 2.6.27 e1000e driver places Intel ICH8 and ICH9 gigE chipsets at risk https://bugs.launchpad.net/bugs/263555 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
