Title:
VAIO freezes at poweroff
Status in linux package in Ubuntu:
New
Bug description:
I have a VAIO SVS1511C5E from 2012. I am on the latest BIOS available
(rev 3.7).
On Ubuntu 24.04.1 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.
