Hello, Benjamin Herrenschmidt asked to re-report this issue to linuxppc-dev and here it is.
[original LKML message http://lkml.org/lkml/2008/12/21/105] Synopsis Plain/non-root userspace application which doesn't interface with any weird out-of/in-tree drivers manages to lock-up a PS3 machine running Linux. The application in question is Mono VM running mcs.exe (C# compiler) which tries to compile particular file, distribution is Yellow Dog Linux 6.0 with either stock (2.6.23.x) or custom compiled (2.6.27) 64bit kernel. Symptoms are as follows (interaction is done via ssh from another machine): $ make ... lots of stdout/err messages ... eventually an error message Eventually the ssh session terminates, PS3 is still pingable but impossible to connect to, attaching keyboard and trying magic SysRq doesn't work, typing keys into login: prompt works (as in - the terminal shows keys that were pressed, but after hittiing enter the carret is advanced and nothing happens, hitting random keys doesn't yield anything either) There's a bug in Mono bugzilla which describes exactly the same problem, but it appears as if reporters machine continued working after hitting the problem. https://bugzilla.novell.com/show_bug.cgi?id=414845 The reporter aslo managed to create minimal reproducible test case (so that running `MONO_PATH=... .../mono .../mcs.exe prob.cs' kills this PS3 just as well) Any pointers to what can be done to further debug this would be greatly appreciated. [ends here] Unfortunatelly reproducing requires building Mono from sources. Mono 2.0.1 can only be built in 32bit mode and still exhibits the same (locking-up behavior): http://ftp.novell.com/pub/mono/sources/mono/mono-2.0.1.tar.bz2 Or the one from the SVN, instructions are at: http://mono-project.com/AnonSVN (Configured with: `CC='gcc -m64' ./configure' (never tried 32bit build)) Unfortunatelly the only PPC64 machine i have access to that's running Linux is a PS3 so i can not confirm/deny the reproducibility on other PPC64's. P.S. FWIW custom 2.6.27 = ps3_defconfig + enabled netconsole. -- mailto:av1...@comtv.ru _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
