Bug ID: 219762
Summary: [regression] power management broke in 6.12 for ECS
BAT-I(1.2)
Product: ACPI
Version: 2.5
Kernel Version: >= 6.12
Hardware: Intel
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: Power-Sleep-Wake
Assignee: acpi_power-sleep-w...@kernel-bugs.osdl.org
Reporter: d...@flaterco.com
Regression: Yes
Affected hardware and firmware:
ECS BAT-I(1.2)/J2900 (mini-ITX with embedded CPU)
DMI: ECS BAT-I/BAT-I, BIOS 5.6.5 09/18/2018
Misbehavior:
Since kernel 6.12, neither S3 nor S5 work anymore. For S5, final shutdown
message is printed but the PC does not turn off. For S3, the display
(integrated graphics) goes black, but the case fan keeps spinning, the power
LED remains solid not blinking, and wakeup events have no effect. Nothing
useful found in log after power cycle. Problem persists in kernel 6.13.1.
Reverting to kernel 6.11 immediately cures the problem.
