Subject: [stable 6.6.y] commit e613904fa419 causes suspend regression
Date: Tue, 19 May 2026 13:51:22 +0900 [thread overview]
Message-ID: <agvqqMt9x0df-WXS@google.com> (raw)
Hi,
We've identified 6.6.y stable commit e613904fa419 (usb: typec: ucsi:
Update power_supply on power role change) (commit 7616f006db07017 upstream)
as a root-cause of suspend failures on some of our laptops. It seems
that ucsi_port_psy_changed() causes:
[ 309.858915] PM: last active wakeup source: ucsi-source-psy-cros_ec_ucsi.3.auto2
[ 309.858917] PM: PM: Last active Wakeup Source: ucsi-source-psy-cros_ec_ucsi.3.auto2
which prevent laptop from entering suspend. Reverting the commit in
question fixes the issue.
