Default Problem with hyperthreading/smp

Hi,

Right the rundown is simple:
I am using gentoo, with the gentoo nvidia drivers emerged. I had everything
working at one point, then I did an upgrade system and my problem started.

Convinced I broke something (I'm fairly new to gentoo), I have done a
brand new stage1 install with nothing particularly customized as yet.
The problem persists. opengl-update ran without a hitch.

Very simply glx and everything works beautifully, except when the applications tries to make use of multithreading.

To give an example, quake3 runs fine, quake3-smp fails.

This has the side effect of causing a failure for all the games that autodetect your smp abilities, for example ut2k4.

UT doesn't give an error, it merely says failed to load opengl library, but
from other apps I managed to retrieve the actual errror:
libnvidia-tls.so.1: cannot handle TLS data

I suppose I could possibly compile an extra, non-smp kernel for gaming use but it seems like a horrid waste of my computers capabilities (which
I did after all pay rather handsomely for) and of course it worked with all
the earlier drivers, the problem only started with 6110

I tried googling for the error message, and the only reply I found
suggest rm'ing the tls directories/files.
Rather than simply doing this, I tar'ed them all up first and tried this,
it merely changed the error to "file not found", so I restored them, this
clearly did not help.

The README has no information on this error, in fact all I could find on searching for tls was a description of what the files are for, i.e. handling multithreaded glx apps.

Any help would be greatly appreciated.

It's the 128MB model.

Default Re: Problem with hyperthreading/smp

I got it fixed, here is the solution in case anyone else needs it:

add nptl to your USE flags.
emerge --unmerge linux-headers
emerge linux26-headers
emerge glibc


Voila.
