Hi,

I re-emerged the world after trying some stupid optimization system wide. I recompiled everything with -O2. Normally, I am a little crazier, but I wanted to have a stable system before turning the funny cflags on again. So, in theory, my current system should be stable, but it is not. The original install date from somewhere in 2005 on the first AMD64 then got upgraded for core 2 quad (I made a clean install for my i7 Ivy, but my desktop is still on the C2Q). So it got upgraded a lot of time to a lot of incompatible deviced, HAL and UDEV versions over the years. It was working, until now

Now, my hibernate is broken, I was to unplug the computer or press reset as everything else get frozen solid, it never go to suspend state but the screen is black, so I have no log. All 3 types or hibernate are broken, 2 of the 3 used to work fine (I stopped using tux on ice, so I can't say if it worked before, but now it does not).

I have 2 NVIDIA cards using the 295.*** driver on a 3.4.0 kernel. It used to work on that kernel, but now it is unreliable. Sometime X does not start the first time, sometime X start fine but apps using OpenGL or VDPAU segfault and sometime, like right now, it just work. I can usually restart X until it work, no reboot are needed.

What I tried:
- etc-update, of course
- env-update
- a second "emerge -e world"
- recompiling the old kernel on top of the new Gentoo
- recompiling NVIDIA drivers a bunch of time
- look at dmesg, if not for the segfaults, it look fine
- using startudev manually
- Ubuntu on an other hard drive, both hibernate and nvidia work as advertised, so it's not hardware
- memtest86+

So, any ideas?
