I answered Attilio Rao <attilio@freebsd.org> in private on a patch he sent me in order to get at least more info. I will test and let you, and list, know the results. > It might also be worth trying the same with 7.3-RELEASE vs. 7.4-BETA1 > (which just came out) see if the same bug was introduced there as result > of an MFC. > > Otherwise, numerous csups with different date= strings in your supfiles > and multiple buildworld/kernel/installs would be required.
