NVChannel(GL): Graphics channel timeout!

Posted by lee Thu, 29 May 2008 03:13:00 GMT

I got my Macbook Pro in February.  For the first two months I had it, I dealt with the error you see in the title of this entry.  The display would freeze and be entirely unresponsive, save being able to move the mouse cursor around.  The dreaded "Graphics channel timeout" error would be written to the log every 12 seconds until I did a hard shutdown.  Eventually, I had my MLB replaced at the Mac store.  After a week of living without it, I had it returned to me with a brand new board installed.  I got the error again the next morning.

Luckily, the latest EFI update has fixed my problem.  Since installing the update (found here), I haven’t had this error occur once.  Today, OSX 10.5.3 is available.  I’ve installed it, and thus far there’s been no hiccups.  Before the EFI update, I was patiently awaiting this release.  There was a lot of talk about this update having the fix for the "Graphics channel timout!" error.  The EFI update is what fixed it for me though.

    Lee, I have no idea what this error you’re getting is. My Macbook Pro is error-free.

    This comment is a total excuse to ask you for some couch space on Wednesday, July 3rd. I’m flying into NYC and need to catch a train down to Philly the next day.

    Give me a shout via email… I don’t think I have yours.

    Swarovski purses are well known by their special crystals and their high quality. Of course we cannot ignore the unique style of the swarovski clutch bags .We have already known that swarovski evening bags are well known not only in USA, but also even in the world. Since years of its beginning in fashion world, swarovski fashion purses have make great efforts in introducing the new era. They believe that creating new crystal clutches which could attract people’s attention and best sold in a short time based on the ideas that the public gives us endless inspiration. So imagination in designing these gemstone purses as well as crystal bridal bags plays a rather important role when it comes to swarovski bags designers. And also inspiration is not easy to get. Designer crystal bags would only achieve by experiencing new thing.
