This is one of the rare events where userspace isn't the problem. 2.6.x needs somebody with good sparc32 knowledge and some spare time... MfG, JBG Well I'm certainly up for helping out in any way I can [if|when] people start working on getting HyperSPARC(s) to work with 2.6 but I'm no programmer I'm afraid. Just a thought, but do people think it would be worthwhile getting some note about the instability of HyperSPARCs, wrt recent kernels, put into the Linux SMP Howto and the FAQ on http://www.ultralinux.org? (btw, just got hold of a set of Solaris 8 CDs to try and move forward with my SS20 but I hope to come back to Debian/Linux at some point) Gary

Maybe... However, most people using sparc32 either follow kernel development (so they know all the facts), or read the archives. Well I guess I'm just a dumb-ass, then...but a dumbass who's looking out to help other dumbasses not make the same mistake I did. Gary

Compile the latest 2.4 from kernel.org and see if that's any better. But as I say, I don't think these CPUs play nicely with Linux at all, unless someone knows different?

Why wouldn't they? Don't all CPUs labeled as SPARC have to meet the SPARC specifications?

It's not all *that* easy. There are optional parts which some CPU implement, others don't. IIRC there's an emulator for some instructions missing from some CPUs in the kernel, so that shouldn't be a problem for userland IFF the kernel was correctly build for the right type of CPU. Then, I'm not sure if the Ross CPUs are properly supported these days. Maybe ask on sparclinux@vger.kernel.org ...

But as I say, I don't think these CPUs play nicely with Linux at all, unless someone knows different? Well...I did a bit of digging and Keith Wesolowski (The Man, it would seem, when it comes to Linux kernel SPARC development) had the following to say as of January and there doesn't seem to have been much more said on the subject in [EMAIL PROTECTED] since then: 2.4 is more or less hosed. I don't plan to fix it, no time. 2.6 boots UP and seems to work as well as SuperSPARC given the limited testing I've done so far. It may be possible later to backport whatever changes are made in 2.6, but frankly I don't recommend to use 2.4. If you want to help development, use 2.6. If you need first rate stability, use 2.2. That pretty much precludes any use of iptables as it depends on kernel 2.4.x and hence renders my new firewall/router machine kinda useless :( Ah well, guess it's going to have to wait in the loft until 2.6.x runs a little more happily on 32bit SMP or I might try my luck with 2.4.x Or I could put Solaris on it... /me ducks to avoid incoming fire Gary
