Performed two upgrades from 22.04 yesterday, both have locked up overnight with the below. It feels like this is the same issue - can anyone confirm for me?

Unless someone knows some trick to getting it back up? These host VMs and the NFS share is purely for some bulk data backups. I will shift them to the kernel mentioned above later today. If this proves a fix, how soon may it roll out? I've got a large number of hosts to move to 24.04 and will be holding off until this is fixed as it's quite a showstopper.
