Probably an interaction with the realtime kernel patch. A Fedora kernel based on 2.6.26.6 (2.6.26.6-49 on fc8) works fine, a very similarly patched kernel that includes the realtime patch does not. The configurations for both are almost the same (today I tried to change some of the most obvious differences and rebuild, with the same result). No problems with 2.6.24.7-rt21. Test: boot, login, plugin an external usb keyboard (Yamaha P250), it is recognized, use qjackctl alsa patchbay to connect it to kmidimon, kmidimon sees only _one_ midi message and that's it. Kmidimon can't be killed after that. -- Fernando -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
