I asked the question to the group because I did not know if they were functionally any different than a traditional CPU. I successfully built my problem port, Tshark, yesterday while monitoring 'top' on another console. I observed that all 4 cpu's were in service for the build and at times were running at 100 percent each. The State column on all 4 occasionally showed a 'pfault' on all 4 but recovered and the build continued to successful completion. > When I experience something like spurious reboots and it is definately > not hardware, then I delete /usr/src and /usr/ports and perform a > complete rebuild. (Yes seriously, and on the Atom's we're talking days, > aren't we :) ) > I have been using this Atom D510 since it was released about 3 years ago. It ran on FreeBSD 8-Stable until about a month ago. I installed an Intel 520 SSD and loaded a fresh copy of a FreeBSD 9 Snapshot. After getting the source and ports tarballs, I used svnup to bring both up to date. I built and installed world and the kernel to bring me up to Stable. I rebuilt all of my ports using Portmaster. The spurious reboot issue existed for the last 3 years when running FreeBSD-8 Stable. I never had the problem building world or kernel. It only occurred when building some ports. Subversion and Tshark more often than others. FreeBSD 9-Stable was frozen when I tried to build tshark, but I was able to build it OK yesterday. Everything hardware related other than the Atom microprocessor and the Intel motherboard itself is new. The OS is now a different version and all of the source was rebuilt monthly. The ports have been been built many times in the last 3 years. Tom -- Public Keys: PGP KeyID = 0x5F22FDC1 GnuPG KeyID = 0x620836CF
