That looks like a new bug, and it is in the new code I added to force BSP to
wait for all APs to enter sleeping state before StartupAllAPs() is called.
How did you reproduce this?
I'm running the following command to start OVMF (qemu-system-x86_64 was
built a few weeks ago, from git master), and I hit the ASSERT about 50%
of the time (the problem being that LockValue is a huge number like
1234567890):

The only change I make when building OVMF is to include
DebugPkg/GdbSyms/GdbSyms.inf in OvmfPkgX64.dsc to allow me to use gdb.
