This message is a reminder that Fedora Linux 34 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '34'.
Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 34 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1931001 Title: Soft lockup due to interrupt storm from smbus Status in Linux: Fix Released Status in linux package in Ubuntu: Incomplete Status in linux-hwe-5.11 package in Ubuntu: Confirmed Status in linux-hwe-5.13 package in Ubuntu: Confirmed Status in Fedora: Confirmed Bug description: Ubuntu 20.04 LTS and Ubuntu 21.04 occasionally boots with very bad performance and very unresponsive to user input on Lenovo laptop Lenovo 300e 2nd Gen 81M9 (LENOVO_MT_81M9_BU_idea_FM_300e 2nd G).
