Bounces,

I am filling in for John S while he is on vacation?

What system is this referring to?

Invoice #?

Linux?  What version of Linux?

Please advise.

Thanks,

Bug description:
In some circumstances it appears possible for the 2.6.27-rc kernels to corrupt the NVRAM used by some Intel network parts to store data such as MAC addresses.
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!)
