I see the same behavior of oopsing right after boot: [...] Freeing unused kernel memory: 216k freed Unable to handle kernel NULL pointer dereference at virtual address 00000000 [...] Just fine when I go back down to k6-3, et al, optimizations. Tyan S2380B VIA KT133A, amd 1.33ghz, regular stepping, no OC or anything. If you want more info, lemme know. Also had some USB weirdness, but I'm going to debug that a bit before I report on it. thx, -jeremy Christian Bornträger enlightened recipients with the following on 11May2001: > > Give the current -ac a spin and tell me if it works/doesnt and if not how > > it fails > > I will test it on Sunday evening, when I get back access to my Athlon. > > Again I am not sure if I had the same problem related to the > compiler-optimizations.
