I assume they are the same when booting 3.0-R? I am still uncomfortable with the idea of debugging a (possibly complex) problem by running 3.0 binaries on a 2.2.x system. It's not designed to work. Maybe it does. Maybe it doesn't. I'd rather you reported the behaviour of 3.0 binaries under a 3.0 kernel and 2.2.6 binaries under 2.2.6 kernel. Call me old fashioned. ;-) >I can't see how newfs would fail (elf) but systat (a.out) >would work perfectly fine under the same kernel if the emulator was >broken... Well, I kinda agree. Bummer. "The signs are clear, but point into the darkness", or some such. >oh, and fsck (a.out), newfs (a.out) and df (a.out) also >work perfectly fine... But, awk (elf) fails? And say, date (elf) works? That would point at FP probs even if, somehow, awk (a.out) still works. And now Robert Nordier thinks FP is involved. I hope he can do better than me, because I think I'm going back to the shallow end of the pool. Good luck! Stephen.
