The machine is pretty much rock-solid in all cases: I have been able to build a variety of ports, and I can even do a buildworld -j3 without issues. Whenever I try to build pcre, the machine shuts down with this message: WARNING: Current temperature (U3 HEATSINK: 82.5 C) exceeds critical temperature (80.0 C)! Shutting down! The file that always causes this is libpcre16_la-pcre16_exec.lo. Pausing the compiler with Ctrl+Z every 1-3 seconds and then resuming it after 5 allows the compilation of this file to succeed without shutting the machine down. nwhitehorn@ mentioned that this could be a problematic fan, but I haven't been able to find it in the machine. Because the machine has been stable otherwise, I don't think this is a hardware issue and it seems to me that this is just a problem with the fcu driver and the way it manages this particular fan. See this thread http://lists.freebsd.org/pipermail/freebsd-ppc/2013-March/006207.html for the original discussion. >How-To-Repeat: Get FreeBSD running on a PowerMac G5, build pcre, and see it the machine shutdown (assuming this is not a hardware problem). >Fix: Unknown, but this particular problem can be worked around as described above. >Release-Note: >Audit-Trail: >Unformatted:
