Thanks for the report. Is this still on ThunderX2?

Do=C2=A0 you have access to those build artifacts?
=C2= =A0

and/or here:

https://kojihub.stre= am.centos.org/koji/taskinfo?taskID=3D1835251

Source for reference:

Can you share more of the log output?
If you can rebuild, can you run it with DEBUG_VERBOSE set on ArmCpuDxe. E.g= .,

This, along with

>=C2=A0 =C2=A0SP 0x00000000476ED840=C2=A0 ELR 0x000000037FD5BDE0=C2=A0 S= PSR 0x80000205=C2=A0 FPSR 0x00000000

taken from below suggests that UpdateRegionMappingRecursive () is
unmapping itself, likely when splitting a block entry.

This affects all ARM builds, not just ArmVIrtQemu so I would like to
get to the bottom of this.


Thanks,
Ard.
