 * When using CPU load balancing on cgroupv2, a pod can fail to start if another pod that has access to exclusive CPUs already exists. This can happen when a pod is deleted and another one is quickly created to replace it. As a workaround, ensure that the old pod is fully terminated before attempting to create the new one.

+* Enabling LUKS encryption on a system using 512 emulation disks causes provisioning to fail and the system launches the emergency shell in the initramfs. This happens because of an alignment bug in `sfdisk` when growing a partition. As a workaround, you can use Ignition to perform the resizing instead.

 * The current PTP grandmaster clock (T-GM) implementation has a single National Marine Electronics Association (NMEA) sentence generator sourced from the GNSS without a backup NMEA sentence generator.
 If NMEA sentences are lost before reaching the e810 NIC, the T-GM cannot synchronize the devices in the network synchronization chain and the PTP Operator reports an error.
