            Bug ID: 200997
           Summary: Suspend stops disk but immediately reawakens on first
                    try. On subsequent suspends, remains asleep
           Product: ACPI
           Version: 2.5
    Kernel Version: 4.17.0
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Power-Sleep-Wake
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

After boot up and log-in, suspend proceeds through shutting off disk drive, and
then immediately reawakens. This is on an amd64 system with Gigabyte 970A-D3P
motherboard. The problem was bisected down to patch 

commit 18996f2db9186cbabe3a7e7085bfb80408b32755

    ACPICA: Events: Stop unconditionally clearing ACPI IRQs during
suspend/resume

This was not fixed in later kernels through 4.18.4.I'm using the Gentoo distro,
but the bisecting was done with the git kernel. It should be said that after
the first attempt to suspend, subsequent attempts work correctly. The problem
always appears after a (re)boot.


Best Wishes,

Bob Gleitsmann
