I never even thought to check that. Likewise, it took me 8 hours to realize the first boot for 30 seconds that I got the first time was with the heatsink off.. Once I realized that, then I got one of those "Hmm, I wonder if...." kind of feelings and sure enough.. > > It all makes sense now.

If the kernel has softupdates compiled in, all sorts of things fail during boot including sysctl and sometimes mount_nfs. If softupdates are active, not just in the kernel, then 'make world' wedges 5 seconds into the bootstrap build of make. This is the same at both 400MHz and 533MHz. Compiling softupdates out has resulted in an (apparently) happy system at 533. The next good question is.. what's up with softupdates? :-] Hmm.. say, that NCR controller you gave me, is that the one that was screwing up on freefall by any chance?
