OK using an image from Chris of dom1 i have been able to semi reliably cause all sorts of corruption including Oopses in dom0 and other domains. This is on 2 different machines one of which is thought to be atleast semi reliable. I first noticed it when doing a bk pull and having bitkeeper deciding that my tree was rather corrupt (in a dom0), but with other domains running. Running while (:) do tar cpf - . | gzip -3vc | cat >/dev/null; done http://www.yuri.org.uk/~murble/boom/ has some output, with the domain0 deciding to try and access beyond the end of device lots, but this could be caused by random memory corruption. Whilst trying to build somthing in dom0 seems a fairly reliable way of triggering it. Also my dom0 only had 48mb or so of ram but plenty of swap. Before the crash i noticed user programs that allocated lots of memory in dom0 randomly segfaulting, including apt-get update and apt-get build-deps. Again the oopsen i get were generally rather random, although i have noticed another possible XenoLinux bug. When you boot with panic=30 it takes ages for dom0 to reboot, far longer than 30 seconds. Even though after the panic it says rebooting in 30 seconds. ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
