Public bug reported: [Impact] With WX3200 and 20.04d kernel the unit freezes on resume
[Fix] commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default") enabled ASPM by default but a variety of hardware configurations it turns out that this caused a regression. Multiple SKUs with wx3200&rx540 gpus encounter the resume&hange issue. Before the real fix is landed, revert commit 0064b0ce85bb first. [Test Case] 1. plug wx3200 on the adl machine and make it as a output. 2. suspend&resume machine 3. check if machine could resume successfully [Where problems could occur] Low, don't make AMDGPU ASPM by default. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux (Ubuntu Jammy) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: New ** Tags: oem-priority originate-from-1952981 somerville ** Also affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: New ** Description changed: [Impact] With WX3200 and 20.04d kernel the unit freezes on resume [Fix] commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default") enabled ASPM by default but a variety of hardware configurations it turns out that this caused a regression. - Multiple SKUs with wx3200&rx540 gpus encounter the resume&hange issues. + Multiple SKUs with wx3200&rx540 gpus encounter the resume&hange issue.
