Public bug reported: [Impact] KIOXIA NVMe has a 10% chance to stop working after S3.
[Fix] Enable ACS quirk on Intel CML root port. [Test] With the patch applied, KIOXIA NVMe always works after S3. [Regression Potential] ACS works at hardware level, so I can't really assess the risk of regression. Since Intel confirmed CML also needs ACS quirk, we can only trust them. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: Confirmed ** Affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: Confirmed ** Affects: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided Status: Confirmed ** Affects: linux (Ubuntu Groovy) Importance: Undecided Status: Confirmed ** Affects: linux-oem-5.6 (Ubuntu Groovy) Importance: Undecided Status: Won't Fix ** Tags: oem-priority originate-from-1893902 stella ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Groovy) Importance: Undecided Status: New ** Also affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-oem-5.6 (Ubuntu Groovy) Status: New => Won't Fix ** Changed in: linux (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux (Ubuntu Groovy) Status: New => Confirmed ** Changed in: linux-oem-5.6 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux-oem-5.6 (Ubuntu) Status: New => Invalid ** Tags added: oem-priority originate-from-1893902 stella -- 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/1895718 Title: Fix non-working NVMe after S3 Status in HWE Next: New Status in linux package in Ubuntu: Confirmed Status in linux-oem-5.6 package in Ubuntu: Invalid Status in linux source package in Focal: Confirmed Status in linux-oem-5.6 source package in Focal: Confirmed Status in linux source package in Groovy: Confirmed Status in linux-oem-5.6 source package in Groovy: Won't Fix Bug description: [Impact] KIOXIA NVMe has a 10% chance to stop working after S3.
