The dmesg output

I have a NVIDIA GeForce 8600GT graphics card. I'm using Gentoo on a AMD64 machine with a custom built 3.5 kernel.

I've been using nouveau for more than a year by now without any kind of problems. Yet, since I enabled the last kernel options I needed to get 3D hardware acceleration, I'm having some issues.

When closing applications like web browsers or video players the X server suddenly hangs (I cannot even move the pointer) and, after a few seconds, it crashes and I see a TTY console. Then, I think, gdm tries to restart it and after a few seconds I have again some graphics on the screen which often is a corrupted image of what I was seeing before the crash. Then X crashes again, gdm tries to restart it and so on.

When I'm on the TTYs I'm having some keyboard issues (keys double-typed or missed) but otherwise they work fine, so I was able to log in and get some dmesg output and X logs, which I'm attaching.

This issue only appears after I suspend and resume the PC. I can trigger this behavior almost at will after a resume but I'm not able to do it before. It also seems to be related to Xorg drivers and/or 3D, since I didn't encounter it before activating hardware acceleration and it only affects the X server, even after a restart, while having no effect at all on TTYs.

If you need more detailed information just let me know.

This should be fixed in 3.6-rc2 by commit 2064db725cc6d4ea19a24c138bc37939b63e3ae6 (drm/nv86/fifo: suspend fix). Sadly, my attempts to get this into 3.5 have been ignored so far.

I tried out kernel 3.6_rc3 and indeed it seems the bug is fixed. Thanks!
