Re: hdparm -t yields incorrect timings when Intel hyperthreading is enabled
While examining the kernel log for another reason, I came across
evidence that acpi_idle, and not intel_idle, is being used on my
dn2800mt system, see below. In fact, it seems that intel_idle cannot be
used. Is there some sort of binary blob involved here?
