Public bug reported: I have a VAIO SVS1511C5E from 2012. I am on the latest BIOS available (rev 3.7).
On Ubuntu 20.04.1 LTS (kernel 6.8.0-41-generic), the laptop hangs during poweroff or reboot. In the logs, the last lines I get are: === sept. 02 18:02:55 antoine-SVS1511C5E systemd[1]: Reached target poweroff.target - System Power Off. sept. 02 18:02:55 antoine-SVS1511C5E systemd[1]: Shutting down. sept. 02 18:02:55 antoine-SVS1511C5E systemd-shutdown[1]: Syncing filesystems and block devices. sept. 02 18:02:55 antoine-SVS1511C5E systemd-shutdown[1]: Sending SIGTERM to remaining processes... sept. 02 18:02:55 antoine-SVS1511C5E systemd-journald[338]: Received SIGTERM from PID 1 (systemd-shutdow). sept. 02 18:02:55 antoine-SVS1511C5E systemd-journald[338]: Journal stopped === At each boot, dmesg displays a bug, which you can see in the attached file "CurrentDmesg.txt" at second 4.745697. My laptop also sometimes gets really slow (I can move the mouse, but launching a new window like the file manager or Firefox or even starting a new shell takes a minute). When that happens, I get a similar error multiple times in my journalctl (see attached file "journalctl logs"). The folks over on IRC (libera #ubuntu) told me it might be a kernel bug related to power management, so I tried different releases. - 14.04 works (does not hang during power off) - 20.04 works - 21.04 works - 21.10 does not work (hangs during power off) - 22.04 does not work - 24.04 does not work I then tried to narrow it down to a kernel release so I tried a few kernels within 24.04.1. - 5.11.0 works (does not hang during power off) - 5.11.16 works - 5.11.20 works - 5.11.22 works (which is called 5.11.0-20 in https://kernel.ubuntu.com/mainline/v5.11.22/ so I'm not sure which version it is) - 5.12.0 does not work (hangs during power off) - 5.13.0 does not work Note that in kernel 5.11 and below, I do not get the aforementionned bug in dmesg, whereas it happens every times on kernels 5.12 and above. I also never experienced freeze in kernels 5.11 and below. (I tried booting with acpi=off in 24.04.1 with kernel 6.8.0, which did not seem to fix the issue.) Kernel 5.12 seems to be the culprit, and I see it added Dynamic Thermal Power Management (DTPM). Could my firmware be incompatible with DTPM? Thanks a lot for your help. Please let me know what I can do to help fix the issue.

My laptop also sometimes gets really slow (I can move the mouse, but launching a new window like the file manager or Firefox or even starting a new shell takes a minute). When that happens, I get a similar error multiple times in my journalctl (see attached file "journalctl logs"). The folks over on IRC (libera #ubuntu) told me it might be a kernel bug related to power management, so I tried different releases. - 14.04 works (does not hang during power off) - 20.04 works - 21.04 works - 21.10 does not work (hangs during power off) - 22.04 does not work - 24.04 does not work I then tried to narrow it down to a kernel release so I tried a few kernels within 24.04.1. - 5.11.0 works (does not hang during power off) - 5.11.16 works - 5.11.20 works - 5.11.22 works (which is called 5.11.0-20 in https://kernel.ubuntu.com/mainline/v5.11.22/ so I'm not sure which version it is) - 5.12.0 does not work (hangs during power off) - 5.13.0 does not work Note that in kernel 5.11 and below, I do not get the aforementionned bug in dmesg, whereas it happens every times on kernels 5.12 and above. I also never experienced freeze in kernels 5.11 and below. (I tried booting with acpi=off in 24.04.1 with kernel 6.8.0, which did not seem to fix the issue.) Kernel 5.12 seems to be the culprit, and I see it added Dynamic Thermal Power Management (DTPM). Could my firmware be incompatible with DTPM? Thanks a lot for your help. Please let me know what I can do to help fix the issue.
