Hi, the following commit (SVN r14372) breaks Windows boot for me on OVMF (x64_build):
Add EDKII_VARIABLE_LOCK_PROTOCOL and the implementation in MdeModulePkg variable drivers. Add code in BdsDxe driver to call the protocol to mark the read-only variables defined in the UEFI Spec. Signed-off-by: Ruiyu Ni <ruiyu...@intel.com> Reviewed-by: Guo Dong <guo.d...@intel.com> Reviewed-by: Star Zeng <star.z...@intel.com> I'm seeing this with - Windows 8 Consumer Preview Build 8250 - Windows 2008 R2 SP1 The preceding commit (SVN r14370) works fine. I encountered the problem at SVN r14393 and tracked it back to SVN r14372. (For Windows 2008 R2 SP1, my OVMF.fd firmware image includes a CSM build of SeaBIOS -- it is a requirement for this OS --, but the CSM is orthogonal to the problem: the CSM is invariably used with SVN r14370 (success) and SVN r14372 (crash).) The problem is a crash (blue screen of death) during boot. Windows 8 Consumer Preview Build 8250 doesn't seem give me more than a laconic BSOD; I took a screenshot. Windows 2008 R2 SP1 is more friendly, it writes a minidump to the disk. At the next successful boot & login (which requires switching back to SVN r14370 of course) a message is popped up with details. I saved all files under http://people.redhat.com/~lersek/edk2.r14372.crash/ should they help with debugging. Thanks!
