2 fails:

//tensorflow/python/debug/wrappers:disk_usage_test (at easybuild/framework/easyblock.py:2819 in report_test_failure)

1 failed for flatbuffers-python pip check (wrong name)

And it seems my Abseil patch didn't work.

EIGEN_STRONG_INLINE Packet16h predux_half_dowto4<Packet32h>(const Packet32h& a) {

This should have been patched.

I'll look into it and merge on top of #26602 hence the draft state
