Screen shot of kernel panic
1. Please describe the problem:
kernel panic on 6.2.7
2. What is the Version-Release number of the kernel:
3. Did it work previously in Fedora? If so, what kernel version did the issue
*first* appear? Old kernels are available for download at
4. Can you reproduce this issue? If so, please provide the steps to reproduce
the issue below:
Yes, happens every time boot is attempted.
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``:
6. Are you running any modules that not shipped with directly Fedora's kernel?:
Don't think so.
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.
The failed boot doesn't show in kernel logs. I have only successful ones going back to 4/2022.The log is 19Mb. See attachment photo.
I can report the same failing to boot issue on our AMD-based reverse proxy. We are seeing “Kernel panic - not syncing: timer doesn’t work through Interrupt-rempped IO-APIC” when using Fedora Kernel 6.2.7-100.fc36.

Possibly GPU related?
Per the Fedora discussion, it appears to affect 1st gen Ryzen systems.
I cannot use the laptop with 6.2.7-200, it freezes after login:
Dell Precision 7560
Fedora Kernel 6.2.7-200.fc36
Fedora Linux 37 (Workstation Edition)
11th Gen Intel® Core™ i9-11950H × 16
Software Rendering / Mesa Intel® UHD Graphics (TGL GT1)
Last known working kernel 6.1.18-200
The previous commenter's issue differs from what the rest of us are seeing, as in that case, the machine boots to the login screen. For the rest of us, the kernel panics before boot up starts.

Please let me know how can I help.
Where can I look for logs or something, I would be happy to help to make it stable since I use this OS to work.
Just to verify, this is still an issue with the latest rawhide kernels as well?
It's still an issue with 6.2.8-200.fc37.
I tried running ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel`` and got "Nothing to do. Complete!". Let me know if there's a more recent kernel you need me to test, and how to go about installing it.
Hi, this continues to be an issue for me with kernel 6.2.9-200.fc37.
This kernel panic condition has now been present in four consecutive updates (6.1.18, 6.2.7, 6.2.8, and now 6.2.9). If I hadn't used 'dnf versionlock' to preserve 6.1.14, I'd have two completely unbootable systems right now. Is there anything I can do to help get this issue addressed?
Issue seems to be addressed in 6.2.11, system boots normally. Thanks!

Just to update my case here. After Fedora issued a BIOS update on my laptop, I don't have any issue anymore. Thanks
I was able to boot using 6.2.12
However, a pop-up appeared asking for my password for running /bin/sh. Not sure what that is all about but seems normal after that.
Thank you for all your efforts. I like to keep up to date.
Based on the discussion linked in comment 1 and various other reports and some research, it seems like this was effecting ACPI revisions < 6.3 in certain configurations, where a bit from ACPI 6.3 not being available was interpreted as the CPUs being offline which lead to the cryptic panic here.
Looks like this was fixed in 6.2.11 by:
x86/acpi/boot: Correct acpi_is_processor_usable() check
