A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=952> ====================================================================== Reported By: skunk Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 952 Category: PCI - emu10k1 Reproducibility: random Severity: crash Priority: normal Status: new Distribution: Debian testing Kernel Version: 2.6.8-2-k7 ====================================================================== Date Submitted: 03-01-2005 06:28 CET Last Modified: 06-07-2006 18:09 CEST ====================================================================== Summary: System freeze at end of MIDI playback Description: Hardware: Sound Blaster Live! Value Software: sfxload (for patch loading) and drvmidi (playback) I often play a list of MIDI files. On a number of occasions---either at the end of a MIDI song, or when I hit STOP---the computer has frozen hard. The recurrence is rare enough to make this more an annoyance than a showstopper, but then, I haven't been too keen on ferreting out this bug. I am reporting this against ALSA from the 2.6.8 kernel, as that is what I'm using now (Debian official package) but the same problem arose with alsa-driver 1.0.8 (as compiled by me) on 2.4.29. I could probably rig up something to start/stop MIDI playback repeatedly, with a debug-compiled driver, but is there any way to get useful debugging output when the bug takes the whole system down? ====================================================================== ---------------------------------------------------------------------- skunk - 04-23-06 07:57 ---------------------------------------------------------------------- This bug is back with a vengeance. I am now running Ubuntu Dapper (kernel 2.6.15) on amd64. I'm using the same Sound Blaster Live! Value board as before, in conjunction with asfxload, aplaymidi, and (x)playmidi. Complete system freezes are frequent with MIDI playback. Usually it's at the end of a song, although on one occasion it happened in the middle. (The active instruments all held the note they were on---kind of a creepy effect, IMO.) I do notice that crashes are less frequent when I play midi through the AWE32 interface (using playmidi -a) rather than straight ALSA with aplaymidi. But, as I found out a few minutes ago, they still crop up from time to time. Is there a document somewhere detailing how I can get a useful trace on a crashed kernel, that might help the ALSA developers track down the problem? This bug is not terribly difficult to reproduce, and I really would like to be able to play MIDI files without worrying about it.... ---------------------------------------------------------------------- pen - 06-07-06 18:09 ---------------------------------------------------------------------- Having the same issue here (it seemed to be triggered by The GIMP - recent CVS builds have a MIDI controller, and the freezes stopped when I disabled it) Kernel - 2.6.15-23-k7 (Ubuntu Dapper) ALSA - 1.0.10-4ubuntu4 Sound Card - Creative Sound Blaster Live! 5.1 Digital Issue History Date Modified Username Field Change ====================================================================== 03-01-05 06:28 skunk New Issue 03-01-05 06:28 skunk Distribution => Debian testing 03-01-05 06:28 skunk Kernel Version => 2.6.8-2-k7 09-19-05 10:10 jdthood Note Added: 0006287 09-19-05 10:19 skunk Note Added: 0006290 04-23-06 07:57 skunk Note Added: 0009441 06-07-06 18:09 pen Note Added: 0010085 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
