I'd like to contribute a completley unqualifide note: When I build a -current kernel with WITNESS and I use the nvidia driver (no= t=20 the GL-Part, just the kernel module and the x-driver) the system freezes=20 without panic or anything else, only a powercycle helps. After removing WITNESS the box is running fine. Now for about 3 Weeks witho= ut=20 any problem..... If I can do any tests please give me instructions, I'd love to help. =2DHarry > > For me, I can run without WITNESS, but I guess that's not how it > is supposed to be.... > > Tomorrow I will reinsert the additional memory and re-enable PAE, > but certainly not WITNESS.
