Here is a kernel-option-related bug. I am using a stock Debian-patched kernel with the standard Debian kernel config, on Pentium M and Pentium 4 machines, + the latest Adeos patch. The Debian kernel configuration file, that has every option enabled and everything as modules, works fine with Xenomai except for one single option which must be disabled: CONFIG_PCI_MSI This option messes with the oneshot timer (timer freezes). (thanks to Gilles to have found this out) Otherwise, my biggest source of problems is IRQ sharing between realtime and non-realtime drivers: this predictably provokes kernel panics. But Jan seems to be working on it. -- Romain Lenglet _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
