What does this Kernal Panic mean?

[JHacker]

Please help me figure out what this means. My MBP has been randomly shutting down. This time, it occured while the screensaver was going and possibly about to go into sleep.

panic(cpu 1 caller 0x001A429B): Unresolved kernel trap (CPU 1, Type 14=page fault), registers:

Sorry mate, I'm hopeless at reading these things, but I'm pretty sure we'd need more info anyway. So, do you have third party hardware installed or connected?

 

[someguy]

It's been my experience that seemingly random KP's (read: no obvious correlation with the use of third-party devices) often are the result of a bad or improperly seated memory module.

I would try reseating the RAM (or having someone do it if you are uncomfortable with the procedure).

Best of luck.

I've had my RAM (2 gigs) in for about a month with no problems, so I highly doubt that it's poorly seated. Have there been any issues with kernal panics caused by having a 23" ACD attached?

A kernel panic is generally an indication that the OS code has tried to access some area of restricted area of memory or of some sort of hardware failure. Generally a kernel panic is the kind of error from which the OS code cannot recover from. Panics are supposed to be a common way of signaling this kind of failure in Unix/Linux

Ok i'm trying not to speak too soon but it seems this was caused by my Sandisk card reader being left plugged into the USB hub on the back of the ACD.

Is it that some hardware components don't like ACD ports/sleep? Anyone have info on this?

Difficult to say. Most kernel panics and blue screens are caused by driver conflicts which create some sort of race condition. A lot of these problems are very difficult to find or even recreate sometimes during development. If you found that it's a piece of hardware that seems to have some relation to the panic, then that's probably the source.

I thought the same thing when I was having issues with my 12" PB having random shut downs/ KPs.

If the RAM is badly seated, it most likely will get worse with time as the laptop moves around. Reseating the RAM would be the 2nd thing I'd try. The first thing I'd try would be uninstalling any weird/beta apps on the system. For example, do you have any system mod apps or stuff like VMWare?
