[Bug 42572] Re: e1000 driver on thinkpad X60/T60 produces latency

[Andreas Oberritter]

Leann, thanks for your warning, but the chipset affected by this bug
(82573) seems not to be affected by the bug which corrupts the EEPROM.

Citing Ben Collins from #256555:
"The 2.6.26 kernel and 2.6.27 kernel have the exact same e1000e driver (one which we downloaded from Intel's e1000 sf.net project)."

So, although this problem has been fixed since months (patch posted by
an Intel employee in Oct 07, patch applied upstream Jan 08, released
with Linux 2.6.25), it obviously hasn't been incorporated into the
version of e1000e which was downloaded from sf.net and integrated into
Ubuntu.

Why is Ubuntu not using the upstream version at all?

According to http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-
next.git;a=history;f=ubuntu/e1000e;hb=HEAD the version used is 0.4.1.7.
The patch I posted for this version before works like a charm. Please
apply it. It is quite annoying to rebuild the driver every time a new
kernel package gets uploaded.

If you don't trust my patch, you might want to ask Auke Kok <auke-
jan.h.kok at intel.com>, who contributed
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1eae4eb2a1c784bf35ee4f8f158cd21cf8c387c1
, to review it.

Thanks,
Andreas
