1. Please describe the problem:

Running sadc (via sysstat-collect.service) triggers a GPF in _raw_spin_lock_irqsave.

2. What is the Version-Release number of the kernel:

kernel-6.8.10-300.fc40.x86_64 and later.

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. kernel-6.8.10-300.fc40.x86_64. The previous working kernel is kernel-6.8.9-300.fc40.x86_64.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Yes, every time.
1. Boot into kernel-6.8.10-300.fc40.x86_64 or later.
2. systemctl start sysstat-collect.service.

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``:
It looks like it's fixed in kernel-6.9.3-200.fc40.

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.

Since it's fixed in 6.9.3, I'll post only the trace for reference:
