Conclusion of thread "Deadlocks with recent SMP current"?

     Good to hear.

     No, *I* am not running FreeBSD 5 anywhere on productive
     systems.  Unfortunaly, the ISP recommended it to this
     particular owner of two systems where I am doing some
     voluntary work in my spare time.

     One of the servers ran 5.1 with an uptime of >200 days.
     There were no indications that 5.2 contained such vast
     regressions in comparison to 5.1.  Even today, the 5.2.1
     errata page does not say anything about SMP issues.

     I would rather downgrade to 5.1 (because I know it works
     reliably on this piece of equipment), but unfortunately,
     somewhere during "make installworld", the install binary
     starts to segfault.

     truss shows that the 5.1 /usr/bin/install calls the new
     fstatfs syscall 397.  AFAICT this could only happen when the
     5.1 install binary is linked against the 5.2 libc.  I suppose
     installworld does not point LD_LIBRARY_PATH at the newly
     build libraries under /usr/obj?  If not, what is the best way
     to ensure that binaries are linked against suitable libs
     during installworld?

     Thanks
