Was this a kernel panic?

[ero87]

Hey friends,

I think I may have just had my first ever kernel panic on my iMac G5, it's been near-flawless since I got it in 2005 but it just started flipping out and asked me to restart it. This was the error log:

Anyway, should I be worrieD? Was this a kernel panic? Is something seriously wrong with my iMac?

Thanks so much 🙂

It was a kernel panic relating to makequeues which seems to be something relating to USB printers. Were you trying to print something at the time?

 

[Eidorian]

Yep, that's a kernel panic. Worry if it happens again and is reproducible.

 

[TEG]

Yes, it was the "hard" Kernel Panic. Kernel Panics just happen. If they happen often, that is often the sign of hardware problems.

It could have been caused by dragging and dropping a bunch of files from your desktop to a usb drive. Thus the makequeues error.
