LIN1021-236 : The panic appears when manually executing the "echo freeze> /sys/power/state" command

Created: May 23, 2021 Updated: Sep 25, 2021

Resolved Date: Jul 12, 2021

Found In Version: 10.21.20.1

Fix Version: 10.21.20.3

Severity: Standard

Applicable for: Wind River Linux LTS 21

Component/s: BSP

Description

Because the f2bddbbe40c950adfde493c929c174bd1ef7ee6a patch causes the imx-pdma0 power domain to fail to enter the runtime PM low power mode, the imx-pdma0 power domain directly enters the power off state when the system suspend is manually executed, but because the csi1_esc_lpcg clock depends on IMX_SC_R_panic_1, this clock appears. The problem only appears when manually executing the "echo freeze> /sys/power/state" command
