Symptom
Hogging of the CPU by kernel_task
Workarounds
Sometimes worked around by a safe boot followed by a normal boot, but the positive effect was rarely (or never) long-lasting.
Diagnosis
Not attempted. With the new Console, I could not get what was required.
Environment
MacBookPro8,2 with 4 GB memory, booting from a hard disk drive on USB 2.0.
Comparisons
Earlier versions of Mac OS X, on the same disk, rarely or never present the problem.
