Bug ID: 215770
Summary: Spurious wakeup from s2idle
Product: ACPI
Version: 2.5
Kernel Version: mainline, linux-next
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
Assignee: acpi_power-sleep-w...@kernel-bugs.osdl.org
Reporter: kai.heng.f...@canonical.com

Originally I filed at AMDGPU gitlab [1], but now it seems to be EC related so
file it here:
[ 60.737155] PM: suspend-to-idle
[ 60.737181] PM: ACPI EC GPE status set
[ 60.737194] PM: Rearming ACPI SCI for wakeup
[16445.761061] PM: Timekeeping suspended for 16384.387 seconds
[16445.761176] PM: ACPI EC GPE status set
[16445.761198] PM: ACPI EC GPE dispatched
[16445.763354] PM: ACPI EC work flushed
[16445.769146] PM: Wakeup after ACPI Notify sync
[16445.769147] PM: resume from suspend-to-idle
[16445.771786] ACPI: EC: interrupt unblocked
[16445.809717] PM: noirq resume of devices complete after 38.173 msecs
[16445.810392] PM: early resume of devices complete after 0.569 msecs
[16445.811040] pci 0000:00:00.2: can't derive routing for PCI INT A
[16445.811045] pci 0000:00:00.2: PCI INT A: no GSI
[16445.811688] i8042: [15041] Interrupt 1, without any data
$ cat /sys/power/pm_wakeup_irq
1
... and it's IRQ for i8042.
Because keyboard wasn't pressed, so "Interrupt 1, without any data" is pretty
accurate. If keyboard was used to wakeup the laptop, there will be some data
shown.
