        src/sys/arch/x86/acpi: acpi_cpu_md.c

Log Message:
When we do the sanity check that a P- or T-state transition was successful,
compare also against the control-field. There appears to be many BIOSes in
the field that report a zero value in the status-field. It is unclear whether
this should be taken as a hint that the status-check is not necessary also
during P-state transitions. If we still see timeouts (EAGAIN), this should
be reverted and the status-check should be bypassed if ps->ps_status is 0.
