IRQ issues are generally I-pipe issues. And RTAI uses (almost) the same I-pipe patch as Xenomai, thus shares the same bugs until they are fixed upstream. Generally. There are currently a few fixes floating around on Adeos-main, and we (Xenomai) have some new report probably regarding MSI. As I think I have seen something about MSI in your config as well, could you try to disable CONFIG_PCI_MSI to check if at least the hangs disappears (given, of course, IRQs line will then not be in conflict again)? Also can you try (unless you already do so) with the latest I-pipe patch for, say, 2.6.23.x? Another hint regard IRQ conflict avoidance: If RTnet (or RT hardware in general) shares some line with a Linux device you may not depend upon (Firewire? USB?), just unload the related Linux drivers. Of course, this doesn't fly if it is your main IDE/SATA device... Note that this IRQ stuff is most likely not RTnet business, so it would be good to move the thread over to Xenomai.
