No woody kernel has amd64 support. You really need an amd64 kernel to run amd64 binaries. Only 2.6 kernels have proper support for amd64. AFAIK upstream did not backport any amd64 changes to the 2.4 kernel series since a long time ago.
What I meant was a recompiled kernel close to the woody 2.4 one. In my experience, running woody on a 2.6 kernel is not very smooth. Yes, I know that for running a proper amd64 system, you want a 2.6 kernel. This doesn't always mesh well with reality though.
GotoBLAS is "Pthreads NOT NPTL", with NPTL being "work in progress" since some time ago. I suspect this might go for several other pieces of non-free software. This is a critical issue for us at work.If you could describe your setup and the specific problems you have with it, I will try to find a solution.
Just saying that we have to support running software that does not support NPTL, including building against binary-only libs.
Programs which have been compiled and linked for the use with linuxthreads should usually also work with nptl at runtime. This is exactly what happens on i386 if you run any 2.6 kernel. An i386 system uses the nptl thread library '/lib/tls/libpthread-0.60.so' if you run a 2.6 kernel and the linuxthreads library '/lib/libpthread-0.10.so' if you run a 2.4 kernel (with the same binaries).
Ok, so this should work then? I'll schedule an upgrade of a node to check it out.
The hard 2.6 kernel requirement does hurt though. /Mattias Wadenstein
