This affects almost all architectures. Reverting 468a9428521e, 2a18da7a9c78, and fcfd2fbf22d2 fixed the problem for me in a couple of test builds, but I don't know if all three patches need to be reverted, or if reverting those patches fixes the problem for all builds, or if the revert is sufficient.
