When the system is in the hardware sleep state it can be woken up from either a GPIO or a GPE. Any of those ACPI events I mentioned will make the EC trigger such a wakeup. When the kernel wakes up it will process the ACPI events and then confirm whether there are any remaining interrupts active. * If no interrupts are active, the system will enter back into hardware sleep state. * If any interrupts are still active then the kernel treats it as a genuine wakeup source that should exit the s2idle loop. What happens with this bug is that the WLAN controller is connected to a design specific GPIO, and when the system leaves hardware sleep state that GPIO is also triggered. This means that two interrupts are active: 1 for that GPIO and 1 for the EC SCI. The firmware update for the WLAN controller fixes it so that the GPIO is not active during resume. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2006458 Title: Frequent wakeups on HP Pro x360 435 13.3 inch G9 using Qualcomm FastConnect 6900 Status in linux-firmware package in Ubuntu: New Status in linux-firmware source package in Focal: New Status in linux-firmware source package in Jammy: New Status in linux-firmware source package in Kinetic: New Status in linux-firmware source package in Lunar: New Bug description: To whom it may concern: I was experiencing frequent wake-ups from s0i3x on a HP Pro 435 G9 convertible [1] using the Qualcomm FastConnect 6900 Soc [2]. The issue is related to FW revision WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.9 that comes bundled with Ubuntu 22.10. It appears the SoC increasingly triggering wake-ups after being suspended for approx. 4 hrs. Read the full story at [4].
