Public bug reported: [Impact] Hotplugging RJ45 ethernet cable only works for one time because ACPI GPE wake doesn't working properly anymore.
[Fix] Always use PME poll to read PCI PME to know if there's wake event. [Test] With the patch applied, ethernet cable can always be detected. [Where problems could occur] PME poll mechanism periodically reads the PMCTRL register, so the power consumption can be slightly higher. The increase will be very low, probably won't be noticeable. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-6.1 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Jammy) Importance: Medium Status: Confirmed ** Affects: linux-oem-6.1 (Ubuntu Jammy) Importance: Medium Status: Confirmed ** Affects: linux (Ubuntu Lunar) Importance: Medium Status: Confirmed ** Affects: linux-oem-6.1 (Ubuntu Lunar) Importance: Undecided Status: Won't Fix ** Also affects: linux (Ubuntu Lunar) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Jammy) Status: New => Confirmed ** Changed in: linux (Ubuntu Lunar) Status: New => Confirmed ** Changed in: linux (Ubuntu Jammy) Importance: Undecided => Medium ** Changed in: linux (Ubuntu Lunar) Importance: Undecided => Medium ** Also affects: linux-oem-6.1 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-oem-6.1 (Ubuntu Lunar) Status: New => Won't Fix ** Changed in: linux-oem-6.1 (Ubuntu) Status: New => Invalid ** Changed in: linux-oem-6.1 (Ubuntu Jammy) Status: New => Confirmed ** Changed in: linux-oem-6.1 (Ubuntu Jammy) Importance: Undecided => Medium -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2028122 Title: Fix unreliable ethernet cable detection on I219 NIC Status in linux package in Ubuntu: New Status in linux-oem-6.1 package in Ubuntu: Invalid Status in linux source package in Jammy: Confirmed Status in linux-oem-6.1 source package in Jammy: Confirmed Status in linux source package in Lunar: Confirmed Status in linux-oem-6.1 source package in Lunar: Won't Fix Bug description: [Impact] Hotplugging RJ45 ethernet cable only works for one time because ACPI GPE wake doesn't working properly anymore.
