After a weird system hang I restarted the ESXI host and ended up not able to boot up of the VM's. The VM had a snapshot and it seems the -delta file of the snapshot got corrupted, or final block was not written to it.
All CID's are OK from what I can tell.
I get below error in vmkernel.log when trying to boot up the VM:
