--- Comment #3 from Zhang Rui (rui.zh...@intel.com) ---
Device (RTC)
{
Name (_HID, EisaId ("PNP0B00") /* AT Real-Time Clock */) // _HID:
Hardware ID
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
IO (Decode16,
0x0070, // Range Minimum
0x0070, // Range Maximum
0x01, // Alignment
0x08, // Length
)
IRQNoFlags ()
{8}
})
Method (_STA, 0, NotSerialized) // _STA: Status
{
Return (Zero)
}
}
the RTC._STA returns Zero, which means it does not exist.
ACPI will not install the address space handler to a non-present device.
This might be the root cause of the issue.
Can you please modify the dsdt table to make it return 0x0F instead, and check
if there is any difference?
