I've gotten Frame to run just fine under Linux and NetBSD's emulation
layer but still not under FreeBSD. NetBSD has NFS-mounted its
/emul/linux directory from my FreeBSD's /compat/linux so they're running
the *identical* Linux configuration. I also NFS-mounted the Framemaker
dir from the FBSD box, so that is identical as well.
I'm not closer to why it crashes under FBSD and not NBSD, but in the
process of comparing ktrace output from both, it looks like either
ktrace on FBSD is not displaying the correct calls. Either that, or the
Linux layer is calling the wrong syscalls. (I've compiled it into my
FBSD kernel rather than loading it as a module to eliminate version
problems.)
I've appended portions two dumps below - just before it crashes on FBSD
and the same area under NetBSD, which appears to be displaying the right
kernel entry-points. Note that FBSD's "mincore" seems to really be
gettimeofday, or things are really confused.
(The kdump/ktrace binaries are built from the same CVS 3.4-STABLE source
snapshot as the kernel. I built a new kdump but it still generates the
same output as below.)
Things appear to be running swimmingly up until it crashes. :) Both the
NetBSD and FreeBSD call traces are largely similar barring the name
printing problems.
