Nevertheless: One problem with compile times in 6.7 was noticed and fixed in mainline; I wonder if that is the same issue as yours: https://lore.kernel.org/lkml/18c6df0d-45ed-450c-9eda-95160a2bbb8e@xxxxxxxxx/ https://git.kernel.org/torvalds/c/31e97d7c9ae3de072d7b424b2cf706a03ec10720 I think there was another issue, but can't remember it from the top of my head. Maybe simply checking if 6.8-rc1 fixes things might be the best.
