At several points in the oneiric cycle, there were mismatched expectations regarding the handling of the toolchain. Despite discussions at last UDS that concluded with agreement that the kernel did not need to check the exact compiler version in use for building out of tree modules, the kernel team expected to use the same compiler version for building the kernel across all architectures for a given milestone, a requirement that the foundations team was not aware of.

The outcome of this session is to be an understanding of any requirements for toolchain stabilization (gcc, binutils) from other parts of the team and a description of any freezes (timelines, scope, and rationale) that need to be applied to the toolchain for precise above and beyond the standard freezes.
