Message-ID: <20020803021437.A20015@cowbert.2y.net> Reply-To: peter.lai@uconn.edu Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG For a long while now (since 4.4), I have experienced random reboots while compiling large things (such as world). I always attributed it to bad ram, but i just put a stick of brand new crucial in today, and decided to do some major i/o testing. It ran ok for a while, and then spontaneously rebooted. On my Fbsd 4.6.1-R-p7 box with 384mb ram, k62-400, via mvp3 chipset, I was compiling a kernel and mod-php4 at the same time. The kernel panic'd with a 'panic: (something): CMAP Busy' I didn't notice the panic until just when it was going to reboot, so I don't know what the (something) was. I looked at some mailng list archives and found a closed PR from 3.0-R regarding this. It is difficult for me to notice the panic(s) because I usually remotely admin the box; it just happened that I was doing this onsite and had access to the console. I don't know how to trace a kernel, but if someone would like more information, feel free to contact me about doing this; it would be nice to know if I should submit a PR at this point. Also please CC: me as I am not subscribed to -stable Thanks. pete -- Peter C.
