Symptom
When booting BladeCenter HS22 or HS22V with Integrated Management Module (IMM) build yuoo84c installed, the blade may hang at the "UEFI Platform Initializing" screen. The hang will be accompanied by the following event in the chassis Advanced Management Module (AMM) log:
   
FW/BIOS, firmware progress (ABR Status) FW/BIOS ROM corruption

Solution
This behavior is corrected in IMM firmware release yuoo91e and newer.
The file is or will be available by selecting the appropriate machine type on the 'Product View' of IBM Support's Fix Central web page, at the following URL:

Workaround
This failure may be reduced by disabling Internet Protocol Version 6 (IPv6) support for the IMM. This can be done via the following steps:
1. Boot the blade to the F1 Unified Extensible Firmware Interface (UEFI) setup screen.
2. Select "System Settings" and press Enter
3. Select "Integrated Management Module" and press Enter
4. Select "Network Configuration" and press Enter
5. Change "IP6" setting to "Disable"
Occasionally, the failure can be recovered by restarting the IMM. If this is not successful, then it is necessary to reseat the blade in the chassis to recover. After a reseat, the blade will boot normally.
