Summary: RTC wakeup from S5 does not work
Product: ACPI
Version: 2.5
Kernel Version: 2.6.30
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
I am trying to get RTC wakeup from S5 to work without success. Wakeup from S1
and S3 is fine though. I think the hardware where I am trying to achieve this
should support it.

Additional information attached: acpidump, dmesg, lspci output; kernel config
