Kernel Panic and Hang with Nvidia Drivers...

[AG Restringere]

Had no problems before and was running Nvidia Driver Version 295.59. Now when Ubuntu updated from Kernel 3.2.0-26-generic to 3.2.0-27-generic and I reinstalled the Nvidia Driver Version 295.59 I had tons of performance issues. There were stutters, momentary hangs and when I checked my Xorg logs I found this:

So I proceeded to update to the newer Nvidia Driver 302.07 which is in BETA but the performance issues went away and I approached normal operation. However, google-chrome had a massive hang that froze the entire screen. Nothing in the Xorg log reported anything out of the ordinary but the Kernel log had the following:

Please help...

[AG Restringere (ag-restringere-deactivatedaccount)]

Update: tried installing the latest Nvidia Drivers 304.22 and it has fixed the issue I was having with waking up from suspend to a blank black screen however there are still major peformance issues. This affects many different Nvidia drivers and is partially due to the Ubuntu 3.2.0-27-generic Kernel.

More information, because the bug affects google-chrome and it hangs or stutters with this problem I ran google-chrome from the command line and keep seeing this recurring error, I don't know if they're related...

THIS ISSUE IS NO LONGER AFFECTING ME

[AG Restringere (ag-restringere-deactivatedaccount)]

I moved to the 304.37 Drivers and this happens to be a Nvidia specific issue I have discovered...

[AG Restringere (ag-restringere-deactivatedaccount)]

This is fixed for me as I now run the R310 series nvidia-experimental-310...
