This issue appears on 7-CURRENT running on HP 6710b. I'm running
kernel where the following options were commented out:
#options PREEMPTION # Enable kernel thread preemption
#options ADAPTIVE_GIANT # Giant mutex is adaptive.
There is issue with the process acpi_task_0. It consumes 96.68% WCPU.

I try to run ktrace -p 6, but the ktrace.out is empty. Any suggestion
how to better isolate this bug?
