Diagnosing a Kernel Panic


1 post in this topic

Recommended Posts

So since moving to a hackintosh I've actually not had many stability issues, just the odd quirk here or there, but in the last two days my system has kernel panicked twice.

 

Now, I'm planning to upgrade to Sierra at some point, so that may fix it I suppose, but I'd like to be sure there's not some more serious issue at work. However I'm not sure what to do when it comes to diagnosing kernel panic logs.

 

Here's the latest one:

I'm just wondering if there's any indication of what might have caused the fault here? It would be useful for future reference as well.

 

The process name corresponding to the fault is backupd, but somehow I doubt it should be able to cause a kernel panic. I'm also pretty sure the last time this happened it was a totally different process, so I don't think the process itself is the problem.

 

So for future reference; how do I actually read this log to trace what really caused the problem? Are there any tools that can turn it into something more informative for someone who hasn't somehow memorised what every address in memory points to?
