assuming I did everything correctly, none of these worked.
When I tried "1)", kernal_task behaved in safe mode, but went right back up when I restarted in regular mode. None of the other options ("2)" through "4)") seemed to make any difference. The disk repair did not show any errors in the disk.
No. Same % usage (around 320%, give or take) whether plugged in or not.
Nothing physically plugged in, no.
There is a printer networked through an AirPort. (Incidentally, tried to print something today and the job never printed. That's unusual.)
Installed an updated version of Adobe Flash a day or two ago. That's all, I think.
I'm overdue to install a couple of updates distributed by Apple for security fixes, MS Word updates, etc.
Yes, it does.
Let's go with the extended test. Your test results should appear in the window in the bottom-right of the console.
Picking up this thread from last night. It took a while to do the "extended test" under AHT. The test, once it finished, said there were "No Problems Found."
So, to summarize:
Tried suggestion (1) - starting in safe mode - and in safe mode the kernal_task behaved normally and took up minimal CPU. But when I restarted out of the safe mode and booted up in normal mode, the kernal_task went back to eating 300%+ of CPU.
No other start-up related fixes had any effect.
Neither the disk repair nor the AHT showed any problems/repair issues.
So, what now?
No. Maybe I should be?

Should I just backup and then reinstall OSX?
