Hello, Has anyone else noticed a similar odd behavior with AMD64 and 9.0 prerelease (as well as RCs and betas)? On my 12 core (2*4162EE) the whole system just freezes quite often without any warning, without any messages being logged. Neither is there any panic message from the kernel. The system just suddenly hangs such that there is no alternative but to reboot using the reset button. At the moment I don't have any further info about the cause of the problem, but quite often the freeze has happened when there has been some network activity. Does anyone have an idea how to start tracking down such a problem? I mean anything in addition to this... http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-options.html Cheers, // jau .--- ..- -.- -.- .- .- .-.-.- ..- -.- -.- --- -. . -. / Jukka A.
