6.14.0-0.rc1.20250207gitbb066fe812d6.19.fc43 kernel log when the system didn't
shut off properly
1. Please describe the problem:
I booted the Fedora Rawhide KDE live image
Fedora-KDE-Desktop-Live-Rawhide-20250201.n.0.x86_64.iso which had the kernel
6.14.0-0.rc0.20250130git72deda0abee6.11.fc42 on bare metal from a USB flash
drive on an hp laptop with an AMD A10-9620P CPU and integrated Radeon R5 GPU. I
used the live image. I selected Shut Down from the Application Launcher menu.
The system showed the Plymouth spinner screen. I pressed Esc to show the
shutdown messages. The normal shutdown messages appeared with the last being
something like Unmounting /oldroot. The screen shut off. The laptop's power
stayed on instead of shutting off. The fan became progressively louder over the
next few minutes. sysrq+alt+b didn't reboot the system. I had to hold down the
power button for 5 seconds to shut off the system.
I reproduced the problem a few times with
Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso which had
6.14.0-0.rc1.15.fc42 and
Fedora-KDE-Desktop-Live-Rawhide-20250208.n.0.x86_64.iso which had
6.14.0-0.rc1.20250207gitbb066fe812d6.19.fc43. The problem also happened when
rebooting. I installed 6.14.0-0.rc1.20250207gitbb066fe812d6.19.fc43 in my F41
KDE installation and shut down. The problem happened after systemd-journald
stopped so I couldn't see what the problem was in the kernel log. I'm attaching
the kernel log with debug added to the kernel command line.
The problem didn't happen with 6.13.1 or earlier, so I guess it was introduced
in the 6.14 merge window before 72deda0abee6. I might try to bisect. The
problem didn't happen in QEMU/KVM VMs in GNOME Boxes, so it might be hardware
related.
2. What is the Version-Release number of the kernel:
6.14.0-0.rc0.20250130git72deda0abee6.11.fc42 to
6.14.0-0.rc1.20250207gitbb066fe812d6.19.fc43
3. Did it work previously in Fedora? If so, what kernel version did the issue
*first* appear? Old kernels are available for download at
https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
Yes. I first saw the issue first with
6.14.0-0.rc0.20250130git72deda0abee6.11.fc42
4. Can you reproduce this issue? If so, please provide the steps to reproduce
the issue below:
1. Download Fedora-KDE-Desktop-Live-42-20250208.n.0.x86_64.iso from
https://koji.fedoraproject.org/koji/buildinfo?buildID=2653640
2. Start Fedora Media Writer
3. Write Fedora-KDE-Desktop-Live-42-20250208.n.0.x86_64.iso to a USB flash
drive
4. Reboot
5. Boot Fedora-KDE-Desktop-Live-42-20250208.n.0.x86_64.iso from the USB flash
drive on bare metal on a system affected by this problem
6. Select Shut Down in the Application Launcher menu in Plasma
5. Does this problem occur with the latest Rawhide kernel? To install the
Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
``sudo dnf update --enablerepo=rawhide kernel``:
Yes
6. Are you running any modules that not shipped with directly Fedora's kernel?:
No
7. Please attach the kernel logs. You can get the complete kernel log
for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
issue occurred on a previous boot, use the journalctl ``-b`` flag.
Reproducible: Always
