Public bug reported: [Impact] Intel I219 ethernet on several HP workstations has a chance to stop working after S3.
[Fix] Increase polling timeout on MDIC ready bit so we wait a bit longer for Intel ME. [Test] Without the fix, the I219 ethernet breaks in 10 S3 cycle. With the fix applied, the ethernet keeps working after 1000+ S3 stress test. [Regression Potential] If the firmware/hardware is _really_ broken, we'll waste a bit more time to wait the device resume. Otherwise no functional change. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Medium Status: Confirmed ** Affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Focal) Importance: Medium Status: Confirmed ** Affects: linux-oem-5.6 (Ubuntu Focal) Importance: Medium Status: Confirmed ** Affects: linux (Ubuntu Groovy) Importance: Medium Status: Confirmed ** Affects: linux-oem-5.6 (Ubuntu Groovy) Importance: Undecided Status: Invalid ** Tags: oem-priority originate-from-1894929 stella ** Also affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Groovy) Importance: Undecided Status: New ** Also affects: linux-oem-5.6 (Ubuntu Groovy) Importance: Undecided Status: New ** Changed in: linux-oem-5.6 (Ubuntu Groovy) Status: New => Invalid ** Changed in: linux-oem-5.6 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux (Ubuntu Groovy) Status: New => Confirmed ** Changed in: linux (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux (Ubuntu Focal) Importance: Undecided => Medium ** Changed in: linux (Ubuntu Groovy) Importance: Undecided => Medium ** Changed in: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided => Medium ** Tags added: oem-priority originate-from-1894929 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/1897755 Title: Fix broken e1000e device 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: Invalid Bug description: [Impact] Intel I219 ethernet on several HP workstations has a chance to stop working after S3.
