Public bug reported: [Impact] Spurious wakeup from s2idle caused by Intel 7560 WWAN device.
[Fix] Keep the device at D0 to prevent the unwanted wakeup. Since PCIe ASPM is enabled, the power consumption impact is minimal. [Test] No more spurious wakeup on s2idle. [Where problems could occur] If the device somehow requires to be power-cycled via D3, this may break the assumption. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.14 (Ubuntu Focal) Importance: Medium Status: Confirmed ** Tags: oem-priority originate-from-1953296 stella ** Summary changed: - Fix spurious wakeup caused by Intel 7560 WWA + Fix spurious wakeup caused by Intel 7560 WWAN ** Also affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-oem-5.14 (Ubuntu) Status: New => Invalid ** Changed in: linux-oem-5.14 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided => Medium ** Tags added: oem-priority originate-from-1953296 stella -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.14 in Ubuntu. https://bugs.launchpad.net/bugs/1956443 Title: Fix spurious wakeup caused by Intel 7560 WWAN Status in HWE Next: New Status in linux-oem-5.14 package in Ubuntu: Invalid Status in linux-oem-5.14 source package in Focal: Confirmed Bug description: [Impact] Spurious wakeup from s2idle caused by Intel 7560 WWAN device.
