Are kernel stress test results displayed online?
Before one of the releases, I remember, kernel stress tests results were online. Now I can't find them. Are they run? (I guess they must be.) Particularly would be interesting to see tests for FreeBSD 8.1-RC2, FreeBSD 8.0-STABLE and FreeBSD-9.0. Also does stress test only cover kernel or device drivers as well?

I don't know about the tests that are conducted as part of the release engineering process, but there are links to some tests at: http://people.freebsd.org/~pho/stress/index.html I don't know how useful these will be -- as noted on the above page, the intended audience is kernel developers, many of the tests are associated with experimental kernel patches, the test results are rarely exactly reproducible, and the tests only cover certain kernel subsystems. The test source code is available, so you could run your own tests if you wanted. You could also look at the tests in /usr/src/tools/regression, or some of the benchmarks and tests in Ports. b. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Does this mean that there were no failures at all for years? The reason why I asked was because I started getting system freezes on 8.1-PRERELEASE under heavy use. Before, 8.0-STABLE was very stable under the same load. So I remembered about kernel stress tests in case they might have higher failure rate after some recent 8.1 changes. But of course there are other factors like, possible NVidia driver updates or maybe memory getting bad, etc. Yuri ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I do not update that list any more, because there is no need IMHO. Are they run? (I guess they must be.) Oh, yes. All of the time. Particularly would be interesting to see tests for FreeBSD 8.1-RC2, FreeBSD 8.0-STABLE and FreeBSD-9.0. There's not much to report, but if you have spare time you could run the test your self. Different HW is always a good test parameter. Also does stress test only cover kernel or device drivers as well? The stress2 test primarily targets the kernel.

Take a look at http://people.freebsd.org/~pho/stress/log/ls.html for problems reported. Most if not all have been analyzed and fixed.

If you have a specific test scenario I'd be happy to try and reproduce it. -- Peter ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I just updated the kernel to RC2, if I get one more freeze I will rebuild and run it as debug. BTW are there instructions how to build debug kernel (8.1) ? Somehow googling building debug FreeBSD kernel doesn't fetch instructions for *debug* kernel, it only fetches instructions for just kernel which I do frequently. I know there should be WITNESS and DIAGNOSTIC options enabled, also coredumps should be enabled. But are there step by step instructions online? Also when the system freezes will it dump core? Or how do I make it to dump core if there is no SEGV?
