The “predicted” on the HWE kernel versions mostly is about them not yet being prepared but are expected to use those version numbers initially. The major version will not change but there always can be issues which require replacement uploads to either the just the HWE kernels but also to their parent (which then requires new uploads to derived kernels. But that is the way SRU cycles work.
As for regressions, if they were known we would not upload them. The changelog lists all changes and individual bug fixes will get notifications when kernels are available in proposed. Again, this is the usual procedure of SRU.
As we got notified about regressions that got released in the previous cycle (2025.06.16) we had to restart the complete 2024.07.14 cycle in week #2. The new predicted kernel versions of the cycle are:
[1] Regression in PCI power management causing issues for PCI pass-through to KVM/QEMU.
[2] Regression in fstrim on RAID10 that leads to kernel crashes (workaround: disable fstrim on boot and/or triggered by systemd).
The changelog lists all changes and individual bug fixes will get notifications when kernels are available in proposed. Again, this is the usual procedure of SRU.
