Crash in _nv026629rm+0x44/0x176 [nvidia]

[Nils Gladitz]

After a 2.6.35 kernel update my laptop seemed to hang when X was about to start.
I'm using nvidia-current (260.19.06-0ubuntu1) [Ubuntu 10.10 maverick].
I could remote login via ssh and got the following dmesg output:

[Nils Gladitz (gladitz)]

This seems to be related: http://www.nvnews.net/vbulletin/showthread.php?p=2355003
Apparently the 4 users that currently complain about this problem are also using maverick so it might be ubuntu specific.

[Magnus Hoff (maghoff)]

This bug affects me as well. Is there anything I should do? Should I dump my dmesg here as well?

[Nils Gladitz (gladitz)]

sudo apt-get purge binutils-gold
sudo apt-get install nvidia-current --reinstall

Fixed this for me (tried on two affected systems ).

[Magnus Hoff (maghoff)]

Fix confirmed.

In other news, my nouveau drivers also stopped working, so I was convinced I had a hardware problem. I haven't investigated the nouveau issue any further.

Thank you. This is a huge load off my mind!

[Paul Tagliamonte (paultag)]

Fix found in the wild, this solution fixed it. Someone should get around to fixing this up. I'm going to triage it.

[Paul Tagliamonte (paultag)]

Rational for High: Causes the system to become unbootable.

[Paul Tagliamonte (paultag)]

I doubt the issue is binutils. I'm going to strip that. Someone add it if it's needed

[Paul Tagliamonte (paultag)]

Upstream seems to be aware -- http://git.exherbo.org/?p=hardware.git;a=commit;h=503c31f463019ccec60e30cbbabaeb5c673a706e -- but that's not a fix.

[Nils Gladitz (gladitz)]

To clarify the reason why I added binutils to the bug report is that the problem only seems to show up when using the (experimental) gold linker to build the kernel module. The problem does not show up when using the "old" binutils ld.

[Paul Tagliamonte (paultag)]

Aye! That actually makes sense, but what binutils-gold does is reduce what's being brought into the link, so let's say with LD (old), if you include "A", it will auto-include "B" and "C". With binutils gold, it may not -- so you need to state you need "B" and "C" as well.

Since binutils is doing it's job "correctly", it's technically an issue with nvidia's build chain :)

[Nils Gladitz (gladitz)]

I'm not too sure but isn't what you mean shared library related and kernel modules don't have those?
