I have been running 5.15.74-1-pve just fine, and am able to boot this kernel release without any problems. 5.15.83-1-pve will hang and require a power cycle to get back into the boot prompt to select another kernel.
I have already tried 'update-initramfs -k all -u' and 'pve-efiboot-tool refresh' without any change.
My systems are running a raid1 ZFS root volume, but not sure that makes any difference?
I have also tried 6.1.2 and 6.1.6, which also have the same problem - I can however consistently boot 5.15.74 without any issues.
