A number of UEFI bug fixes were committed over the last quarter, further improving compatibility with different UEFI implementations. Specifically, on some of them &os; failed to boot with an "ExitBootServices() returned 0x8000000000000002" error. This has been fixed with a retry loop (as required by UEFI), in r292515 and r292338.

UEFI improvements from other developers have recently been commited or are in progress. These include support for environment variables set on the EFI loader command line, improved text console mode setting, support for nvram variables, and root-on-ZFS support.
