Hi Aubrey,
My test machine has an invalid cstate->cs_type with the new
C4 support. The type is not system_hardware nor fixed_io.
This is probably from C4. I do not know what the type value is.
if (type == ACPI_ADR_SPACE_FIXED_HARDWARE) {
...
} else if (type == ACPI_ADR_SPACE_SYSTEM_IO) {
...
} else {
cmn_err(CE_WARN, "!_CST: unsupported address space id
type\n");
}
The machine then hits an ASSERT in turnstile_block called
by cmn_err(). The ASSERT is probably failing because
only CPU 0 have been brought online so far.
Regards,
Bill
