If your ESXi host update from v4.1 to 5.1 stalls, crashes or freezes on 22% don't panic wait for it to finish if no joy then next time don't forget to untick disable DPM box in the upgrade wizard, works for me every time.
When it happened first time, I remotely accessed the host and found esxi host frozen on loading screen (black & yellow) on Power management services.
Thanks so much for posting this up! I experienced this on an HP DL580 going from ESX 4.1 to ESXi 5.1. Hung at 22% for about an hour and a half. Cancelled the remediate task and rebooted the host. Upgrade finished successfully. On the next host, I unchecked that DPM box and no issues.
