Running the folding client and blender: 2.6.8.1-bk2 is the last kernel without _any_ swapping problem (no screen freezes etc) | | 2.6.9-rc1 and three -bk forward have oopses and loss of keyboard in X. Can't test them. | 2.6.9-rc1-bk4 is the first functional kernel where the freezes show up. So it is a real regression. Mvh Mats Johannesson
