    This happens to me too periodically. It appears to happen when I wake from sleep and plugin a my microsoft wireless keyboard. Can anyone else comment on what sort of usb devices they have hooked up when this happens?

    i get this same error as well, but i don't use any USB peripherals. maybe it's a built-in HID incidental to this?

    This problem happens to me frequently! Every day.

    No change with any of the Software Updates. Now on 10.5.4.

    7/07/08 11:09:43 PM /usr/libexec/hidd[28] IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8)

    I have also had on 2 occasions, the screen image went crazy with colours and shapes all over the place that all changed when i was moving the mouse around.

    These slow downs/freezes often seem to happen when I am using the program EyeTV, often saving or editing files (4-8gb in size) to the internal hard drive. EyeTV is permanently running on my machine and is the latest version.

    Would appreciate any tips...

    Just want to add that this is happening on my new Macbook Pro running Leopard. Same symptoms, IOHIDEventQueueEnqueue errors repeatedly, graphical anomalies, freezing, symptoms occurring shortly after startup. I thought HID typically referred to input devices, so the new trackpads would make sense as a culprit, but that wouldn't explain the graphical anomalies. Apple needs to figure this one out quickly.

    I'm having the exact same issue as well. Extremely annoying.

    Happens daily, twice daily occasionally. If I wanted a computer that would crash daily, I would have remained with Windows.

    I have the same problem that EVERYONE has in this discussion board.

    "Error enqueuing memory. (0xe00002e8)", which comes quite frequently.

    Random colors and polygons appearing, but this happens to me when I unplug my cinema display from the DVI port. The screen turns blue for a couple of seconds (which it should do), but then it comes back with the crazy polygons. Plugging the cinema display back in just puts the crazy colored polygons all over that screen as well. I took this in to the apple tech at my university and he replaced the logic board, but that didn't change anything. I still get the same problems.

    I also have the problem where the system hangs for 15 seconds, lets you use it normally for 10 seconds stalls again for 15.... and this repeats indefinitely until forever until you restart the machine.

    I don't know if these problems are intrinsic to the hardware, or just a conflict with software... but whatever it is, it is a very serious problem and shouldn't be taken lightly. I don't know if Apple is aware of all these problems, but we should make sure because these MBPs are expensive machines. I f any of you encounter the problem with the colored polygons, take a snapshot using apple-shift-3. I have a number of snapshots to document the error on my machine.

    maybe it would help show how serious this problem really is by posting images. 9714 4322

    We need something done about this. This problem is obviously not isolated to one machine... it's a problem with the ENTIRE penryn MBP line. As I said before, I've had my logic board replaced, and I still have these problems. When I brought the machine in, the tech said that my video RAM was getting currupted and that maybe that was due to defective hardware. It's still defective, which leads me to believe it's intrinsically defective.

    That is exactly what I experience.

    Here's a screenshot from the Laptop screen - the external display also shows a similar sort of view...

    Quite a weird problem!!!

    Here is a video of what happened when my screen image went crazy... combined with the IOHID error as well when I checked after rebooting:

    I have this problem to Freezes then runs for 2-3 sec and in the end freezes totally:

    Anyone found what is causing this problem?

    Can someone with a mbp with less than 90 days call the tech support and share the support obtained with us?

    Hi all,

    I'm also suffering from this I'm using the following script as a temporary work-around, which seems to save me from most, but not all, of the freezes:


    while true; do
    sleep 10
    if [ ! -z "$(sudo tail -10 /var/log/system.log | grep 'IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8)')" ]; then
    killall hidd

    ... I start this from my .profile (as I always open a Terminal pretty much as soon as I log in, this works for me ;)):

    if [ -z "$(ps -aef | grep -v grep | grep kill_hidd)" ]; then
    nohup sudo kill_hidd &

    ... I have to sudo it, because I work from a non-admin account. If you run this from an admin account, you may not have to sudo the task, but I haven't tried that yet.

    Hope that's of some help to some of you

    And I'm really REALLY hoping that Apple sorts this out ASAP - its making me look bad in front of all my Windows using colleagues LOL

    Oops! The formatting screws the script up ... couldn't find anything in Help on how to post unformatted text - could someone clue me in, then I'll post again ...
