I think I've found the problematic module! Please confirm this works: sudo modprobe -r snd_seq_virmidi sudo modprobe snd-rtctimer
I think snd_seq_virmidi is the problematic module because it's used by snd_emux_synth and snd_emu10k1_synth which I don't use at all. In my last post I said that snd_emu10k1_synth was the problem, but after removing that module my system crashed as well 10 minutes after using MIDI. After removing snd_seq_virmidi, it always works for me so far. Also, I think snd-rtctimer has something to do with it: Whithout loading/unloading it manually, it seems to be loaded each time it works, and not loaded each time it doesn't. -- Hardlock of entire system (Dapper Flight 5) https://launchpad.net/bugs/34831 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
