    I also have the same problem with my Macbook Pro 17" HiDef. Very annoying as i have to reboot to clear the multicoloured graphic screen crash. The even log shows:

    Have been running 10.5.5 for 50h now and it still up, but have not pushed my MBP that hard, have some work I need get done before i crash again. I had on nVidia warning but the computer survived.

    kernel[0]: NVChannel(GL): Graphics channel timeout!

    By reading other threads out in the forums it still look like people are still having the same problems. It kinda make sense if the problem is the hardware. You really have to create good drivers to compensate for that....

    Has anyone had any resolution for this problem?

    It is immensely frustrating for this to happen at least twice a week if not more (sometimes twice daily).

    I have the exact same problem as reported earlier, where the user input will be ignored for short periods as kernel_task maxes out the cpu usage. Console also shows streams of "IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8)" messages. It would be very nice if someone from Apple could at least acknowledge this problem, since it seems to be happening to a decent amount of users.

    Has anyone had any luck finding a resolution for this, or identifying anything as a trigger? I have so far been unable to determine any sort of cause, as it seems to happen quite randomly. The only thing I have noticed, is this always seems to start happening after waking from sleep. I have never had the machine do this fresh from a reboot without sleeping. Does this fit with other experiences?

    If there are no suggestions here in the next few days, I'll try and take a trip down to my local Apple Store to speak with the Geniuses about it and see if there's some way to get comment from Apple about this.

    In terms of specs, what machines have people been encountering this on? It would be interesting to see if it's limited to one series. I am using a 2.4Ghz MacBook Pro 15" purchased in May 2008 with no hardware upgrades/modifications.

    Hi all,

    Regarding the graphic glitches it seems it is related to faulty NVIDIA GeForce 8600M GT graphic processor. I've found that apple is offering free repairs to affected users.
    You can find the repair program here:
    I will be calling them and have mine fixed.

    I realize it's been several years, but I'm having the same problem on 10.5.7 now.

    I'd recommend you change your script to call:
    sudo killall -HUP hidd

    this will kill hidd, and restart it (hidd on -HUP signal will force a restart), this is good, as hidd (the Human Interface Daemon) is a useful daemon to have !!!
