No doubt - I'm running 7.0-current: [82]arm9# uname -a FreeBSD arm9.cicely.de 7.0-CURRENT FreeBSD 7.0-CURRENT #12: Thu Dec 6 02:39:25 CET 2007 ticso@arm9.cicely.de:/data/builder/arm-p4-running-2/src/sys/arm/compile/FBOX arm [83]arm9# uptime 10:02PM up 690 days, 19:43, 1 user, load averages: 0.29, 0.22, 0.15 Including named, although not on exactly this machine. This one is even compiled O2 - with a few hand selected exceptions. Compiling perl fails with sig11 as well, but I hadn't verified this problem any further. > The one caveat is that I've found bugs in the atomic routines in the > past, and have had people submit fixes as well.

Of course this won't rule out all possible atomic cases. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
