1. Please describe the problem:

Cockpit has an automated test for Kdump to NFS, this test failed after updating 

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

kernel-core-6.4.16-200.fc38.x86_64.rpm
kernel-modules-core-6.4.16-200.fc38.x86_64.rpm

3. Did it work previously in Fedora? 

This worked in Fedora-38 without updates-testing

kernel-modules-core-6.4.14-200.fc38.x86_64
kernel-core-6.4.14-200.fc38.x86_64

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

We have an automated test for this: https://github.com/cockpit-project/cockpit/blob/main/test/verify/check-kdump#L389

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``:

Rawhide can't be tested as it suffers from https://bugzilla.redhat.com/show_bug.cgi?id=2112782

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
