First of all, thanks for your time. > One bug report can track a problem across several packages, so there's no need for multiple reports.
Sorry for the noise :-) > If you can reproduce it with Hirsute I can reproduce the problem using linux-image-generic 5.10.0.14.16 from hirsute in a tty. To be sure I did it right, those are the steps I followed: 1. added this repo to the list of repos: deb http://archive.ubuntu.com/ubuntu/ hirsute-proposed restricted main multiverse universe 2. updated apt list and installed those packages: linux-headers-generic/hirsute-proposed linux-modules-5.10.0-14-generic/hirsute-proposed linux-modules-extra-5.10.0-14-generic/hirsute-proposed linux-image-5.10.0-14-generic/hirsute-proposed 3. Rebooted, choose kernel 5.10 from advanced list in grub 4. On gnome login prompt, switched to tty with ctrl+alt+F3 5. Check kernel and packages: $ uname -a Linux bestia3 5.10.0-14-generic #15-Ubuntu SMP Fri Jan 29 15:10:03 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux $ dpkg -l | grep 5.10.0 ii linux-headers-5.10.0-14 5.10.0-14.15 all Header files related to Linux kernel version 5.10.0 ii linux-headers-5.10.0-14-generic 5.10.0-14.15 amd64 Linux kernel headers for version 5.10.0 on 64 bit x86 SMP ii linux-headers-generic 5.10.0.14.16 amd64 Generic Linux kernel headers ii linux-image-5.10.0-14-generic 5.10.0-14.15 amd64 Signed kernel image generic ii linux-modules-5.10.0-14-generic 5.10.0-14.15 amd64 Linux kernel extra modules for version 5.10.0 on 64 bit x86 SMP ii linux-modules-extra-5.10.0-14-generic 5.10.0-14.15 amd64 Linux kernel extra modules for version 5.10.0 on 64 bit x86 SMP Now, calling 'sensors' from console still causes the problem, i.e. the output of sensors hangs a couple of seconds just after printing 'amdgpu-pci-0100' and the fans start spinning. The only difference with kernel 5.10 wrt kernel 5.8 is that I don't see the kernel error messages directly into the tty, but they are present in dmesg: [ 25.039603] vboxdrv: TSC mode is Invariant, tentative frequency 2592005345 Hz [ 25.039607] vboxdrv: Successfully loaded version 6.1.18 (interface 0x00300000) [ 25.251013] VBoxNetFlt: Successfully started.
