Please mark bug #13187 as a dup of this bug.
I sent two separate emails because nobody replied to the first one.
Sorry for the duplication.

Fixed by:
commit 62cedd11f63c99efd2962fb69763a09e2778f6e6
Author: Matt Carlson <[email protected]>
Date: Mon Apr 20 14:52:29 2009 -0700
tg3: Fix SEEPROM accesses
The recent NVRAM patches sanitized how the driver deals with NVRAM
data, but they failed to bring the SEEPROM interfaces inline with
the new strategy. This patch brings the SEEPROM interfaces up to date.
This patch also reverts commit 0d489ffb76de0fe804cf06a9d4d11fa7342d74b9
("tg3: fix big endian MAC address collection failure").

I saw this warning with certain GCC versions for several kernel
cycles, so it's not any recent change that triggers this and it is
not a regression.
GCC is simply wrong here - i have posted a workaround for that but
it is too ugly to be merged upstream.

This patch regresses on older GCC versions and doesnt really address
the GCC false positive warning either, it just removes the inline
function that triggers the warning.

OK, so this is not a kernel bug in fact. I'm going to close it.

I don't think that's correct. There's been a demonstration that some gcc
versions don't inline as many memcpy as without the patch, but
that's not necessarily a pessimization. In fact 64bit used
the same gcc based memcpy forever and there's no indication that
the 64bit kernel runs slower than the 32bit kernel because
of this (in fact I have some indications that the 64bit kernel
runs faster)
Also the general trend in the kernel is to inline less
things because it has been demonstrated many times that
the function call overhead isn't that great, so I don't
see why memcpy should be different from all other
functions in this regard.
What Linus asked for was a demonstration that there's
no catastrophic regression (as in no trivial cases inlined anymore)
and I think that was demonstrated by the numbers.
Also the patch definitely shrunk the kernel and at least the
standard wisdom is that for micro optimizations icache optimizations
are the most useful one. In this sense the patch was a improvement.

Interesting sophistry.
Yes of course the patch doesn't fix gcc -- the goal is to remove the warning
message (and also quite some ugly obsolete code) from the kernel build, not
fix gcc.

This has been fixed by commit dfc15e8955338fedf5c5d15622c4042c1e4ee332.

Can you elaborate the issues you're seeing with UXA+KMS? EXA had some
breakage in several configs, though it shouldn't have caused gem_idle
warnings (those are real bugs I think).
Cc'ing Eric since this is more his area.

I'm curious about this one... we pushed some display setup related
fixes recently so things should be working well in all configs now
afaik.
Alex can you post your X log?

Hi Jesse,
Sure thing - and to be complete I retried with the latest git kernel,
along with the latest Xorg updates from the OPENSUSE 11.1 Xorg repository.
On my system the default displaymanager configuration contains
DISPLAYMANAGER_RANDR_MODE_auto="1024x768_60 64.11 1024 1080 1184 1344
768 769 772 795 -HSync +Vsync"
With this setting running in KMS+UXA, kdm starts up with a garbled
screen, and I soon get a soft lock-up after trying to blindly entering a
username/password. With any other setting, I got the mouse cursor but
soon followed by a black screen and soft lock-up (No activity from
caps-lock, but Alt-SysRq still worked). These settings work fine without
KMS when just using EXA.
Here is the display-manager log, I tried starting up using a few
different modelines from my xorg.conf:

Ooh that sounds bad. Can you check out
http://intellinuxgraphics.org/how_to_report_bug.html and file a bug at
freedesktop.org for this? That way we won't lose it, and we'll have
all the info in one place.
Eric, do you know of any changes recently that might affect the
gem_idle warning Niel sees here? Seems like in any UMS config the GEM
lists should be clear at VT switch time...

Given the stack for the initial report, why would a config other than
enabling CONFIG_DMA_ENGINE help if there's no ifdefs involved?
This is happening in the for_each_possible_cpu() loop within
dma_channel_rebalance(), which makes sense since the machine boots fine
normally but not with `nosmp'.
channel_table[] is not being initialized per-cpu for non-online cpus?

Wu Fengguang <[email protected]> is hitting it as well (Subject:

Unless Eric (or Peter) get a wiggle on, we might need to merge the
GFP_NOFS thing.

Still open as "can't reproduce" on my end. Stephen can you reproduce
with the following patch to confirm that the cpumasks are sane?
