LKP framework can guarantee that all the software environment are same on AMD and INTEL platform.
INTEL platform always work well, after revert this patch, AMD works well.
we tried below commit on AMD.
1) 25de7691a0e27c29c8d783a22373cc265571f5e9: bad
2) a82235843b102202766115e10003c9465a8b83ae: good
the error logs(build/CMakeFiles/CMakeError.log) has no difference b/w 1) and 2) on AMD platform
Thanks
