[Fix] Below commit fixes this issue https://patchwork.ozlabs.org/project/intel-wired-lan/patch/20220508070905.1878172-1-sasha.nef...@intel.com/ [Test] Verified on the target machine, and confirmed the issue is gone. [Where problems could occur] The impact is low, it keeps the GPT clock enabled for CSME when e1000e_pm_resume() is called. I can't see this may introduce any regression. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-5.17 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Jammy) Importance: Undecided Assignee: AceLan Kao (acelankao) Status: In Progress ** Affects: linux-oem-5.17 (Ubuntu Jammy) Importance: Undecided Assignee: AceLan Kao (acelankao) Status: In Progress ** Tags: oem-priority originate-from-1971938 originate-from-1971942 somerville ** Also affects: linux-oem-5.17 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem-5.17 (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: linux-oem-5.17 (Ubuntu Jammy) Status: New => In Progress ** Changed in: linux-oem-5.17 (Ubuntu Jammy) Assignee: (unassigned) => AceLan Kao (acelankao) ** Changed in: linux-oem-5.17 (Ubuntu) Status: New => Invalid ** Changed in: linux (Ubuntu Jammy) Status: New => In Progress ** Changed in: linux (Ubuntu Jammy) Assignee: (unassigned) => AceLan Kao (acelankao) ** Tags added: oem-priority originate-from-1971942 somerville ** Tags added: originate-from-1971938 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1973104 Title: e1000e report hardware hang To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1973104/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
