Hello Cascardo. Here you will find dmesg.tgz with:
dmesg/dmesg-2021-05-07-08-22.txt dmesg/dmesg-normal.txt dmesg/dmesg-unresponsive.txt dmesg/dmesg-2021-05-20.txt dmesg-normal.txt is a full dmesg when the computer works fine. dmesg-unresponsive.txt is a full dmesg in which the computer boots and very soon becomes unresponsive to trackpad and even you can type faster than computers manages to process. Usually this happens on the first boot after a full day with the laptop shut down. dmesg-2021-05-07-08-22.txt and dmesg-2021-05-20.txt are full dmesg in which you can see the message CPU# stuck for 22s! When this happens nothing works well. I even deployed a small script to reboot the laptop when this happens. We are an school with hundreds of desktops and laptops with ubuntu 20.04 without problems. But we have received a big number of this lenovo laptops that does't work well with ubuntu 20.04 or 21.04. I don't know if it may help you but with Fedora 34 the laptop works fine. Thank you for your attention. ** Attachment added: "dmesg.tgz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1931001/+attachment/5502949/+files/dmesg.tgz -- 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/1931001 Title: kernel: watchdog: BUG: soft lockup - CPU#3 stuck for 22s!
