Hi Neil, Please include both fixes in mdadm 3.2.1 release: RE: [PATCH 1/2] imsm: remove OEM table from detection of OROM and EFI. RE: [PATCH 2/2] imsm: reading of UEFI variables needs an update The first one removes OEM parameter table reading. We no longer scan OROM for "$OEM" string or read EFI "RstScuO" variable. They do not contain the information that we are looking for. The second one sets correct directory and file name for EFI RST version table. The fixes are a minor change to mdadm as whole, but enable proper handling of EFI/OROM information.
