Does portion of 'devinfo -rv' similar to the snippet below show 'est'
attached to both CPUs?
<...>
cpu0 pnpinfo _HID=none _UID=0 at handle=\_PR_.CPU0
ACPI I/O ports:
0x1014
0x1015
acpi_perf0
acpi_throttle0
coretemp0
==> est0
p4tcc0
cpufreq0
cpu1 pnpinfo _HID=none _UID=0 at handle=\_PR_.CPU1
ACPI I/O ports:
0x1014
0x1015
acpi_perf1
acpi_throttle1
coretemp1
==> est1
p4tcc1
cpufreq1
