58 You have a good point but there is a problem. Some of the kernels I
59 tried ran on this machine with uptimes of several weeks and not one lock
60 up. It could be some upgrade that affected this but who knows what that
61 was since I have updated a lot. As for nvidia, I tried both versions
62 that work with my card that are in portage. I got the same with that no
63 matter what I tried.
64
65 As for .39 kernels, I mentioned in this mess somewhere that I had
66 upgraded but ran into problems with that series so I deleted them. I
67 may just be adding to the problems I am having if I do upgrade again.
68 But since I got to try something, I'll try the latest .39 and see what
69 it does.

71 I remember having this type of problem once before. It turned out to be
72 a gcc problem if I recall correctly. I went back a version of gcc and
73 then did a emerge -e world. After that, things worked fine. Thing is,
74 I have had the same gcc since I built this rig according to genlop.
75
76 Weird.
