For me the Fedora 1 CD kernel is ok, 2.4.23 is solid, but the 115 errata kernel for Fedora is unusable, and so bad I swapped to 2.4.23
Fedora Core 1 kernel was 2115. I take it you mean the 2129 errata is unusable ? Why so ?
Keeps crashing, unfortunately only in X11 so I've got a trace off it. If I get more info it'll appear in bugzilla
