So, I've been having serious stability issues with my setup ever since I tried to fix the blue-people problem with adobe flash (namely, that the latest and last version of flash has color layers swapped unless you enable hardware acceleration and export "VDPAU_NVIDIA_NO_OVERLAY=1"). Ever since, I have consistent problems with EQ overflow: the screen starts flickering, then the X server hits 100% CPU, and the system freezes (or X is nice and spares me a hard reboot by just crashing). My /var/log/Xorg.0.log is full of stuff like this:
Code:
[306171.113] [mi] EQ overflowing.  Additional events will be discarded until existing events are processed.

[306171.182] [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.
[306171.182] [mi] mieq is *NOT* the cause.  It is a victim.
[306172.638] [mi] Increasing EQ size to 1024 to prevent dropped events.
[306172.638] [mi] EQ processing has resumed after 51 dropped events.
[306172.638] [mi] This may be caused my a misbehaving driver monopolizing the server's resources.

Also, dmesg is full of stuff like this:

kernel is 3.5.0-gentoo, nvidia-drivers is 290.59-r1. I cannot use the 3xx nvidia-drivers: the X server lasts maybe five minutes before crashing out.

Are any of these problems familiar? Is there any way to stop having the nvidia driver be so unstable? Are there workarounds?

Cheers,

EE
