NVDA(OpenGL): Channel timeout!

[qb84]

I used to have this issue before but nothing like now. It happens way too often with 10.8.3. The screen gets frozen, the cursor moves and audio keeps playing (if i'm playing music) so it is not a kernel panic. I can't do anything else but reboot the computer. Has anyone else experienced this? I'm using iMac12,2 smbios (not sure if this helps at all). The console log shows a bunch of errors right before the BOOT flag so I'm guessing this has something to do with it.

(reboot here)

My video card is:
GeForce GTX 560 Ti 1024 MB

Any ideas?

Thanks!

Hi
I have this same issue with 10.8.3. Because i think the old 10.7.xx Fermi freeze come back with this update. 10.8.2 is rock solid with Nvidia 5xx cards. This update is very much useful with Nvidia 6xx cards. We, the 5xx card holders have to wait next update of Nvidia or Apple some times TONY to solve this problem or change the GPU to 6xx .

All 5xx Nvidia GPU owners keep your 10.8.2 for Maximum performance. please not update to 10.8.3

Yeah I know, 10.8.2 was great. This one I can't use the machine for more than 10 minutes without freezing. Thanks for the tip. I will go back to 10.8.2.

I am getting the same errors with a GT640, but I had them randomly on 10.8.2 also.

Can anyone confirm that 10.8.3 is using drivers utilizing aspects of 10.7 drivers in regards to 5xx fermi cards? If that is the case couldn't we just update to 8.3,then using a kext installer, install the solid drivers from 10.8.2?

If you find a solution let us know. I havent been able to use my installation anymore. Every 10 mins or so it just dies.

I had this problem too, switched to a different SMBIOS and it went away. The MacPro5,1 works the best for me. (if you try MacPro5,1 or 4,1 delete AppleTyMCEDriver.kext from the Extensions folder) Try different SMBIOS's till you find a stable one, hopefully it works for you.

This is same error what I have if i use 660ti or Gtx 260 I must delete AppleGraphicsPowerManagement.kext after delete no error. Now i use 7970 HD and no problem.

Hi qb84,

your problem is discussed here :

With the solution of post 84
http://www.tonymacx86.com/mountain-...ack-latest-drivers-10-8-3-a-9.html#post579250
I got rid of nvda channel timeout with an imac11,1 profile.
Also you may have to try to patch key>GFX0</key or key>Vendor10deDevice1200</key
(worked here with gfx0 only)


My card is the msi version of 560 ti

A+
JJ

Cool, i'll check that out. Sucks though, in 8.2 everything worked great, 8.1 too. After I upgraded to ML I hoped I wouldn't have to make constant kext edits. As an alternative to the vlc "fix", I have been keeping my p2p client up front, the updating stats seem to keep my graphics from going idle enough to freeze.
