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: 07-04-2006 07:20 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? ====================================================================== ---------------------------------------------------------------------- phorn - 07-04-06 04:58 ---------------------------------------------------------------------- The patch seems to at least have made the crash less frequent for me (i.e. I haven't run into it yet). The .deb packages didn't seem to compile for 2.6.17.3, but the Hg sources do work. amarsh04, you will likely get more information if you play from a text-mode console. To do this, hit Ctrl+Alt+F1 to bring you to the console, login, and use aplaymidi like in X... If you want disk activity, switch to ctrl+alt+F2 and cat a bunch of files, then return to ctrl+alt+F1. Hopefully, when the crash occurs, you will get a lot of output on your screen (which was hidden when running in X), and you can take a picture or copy the panic screen. To return to X, hit Ctrl+alt+F7. ---------------------------------------------------------------------- amarsh04 - 07-04-06 07:20 ---------------------------------------------------------------------- I had already tried using aplaymidi in single user mode backgrounded then running a disk intensive task and still had lockups. By booting into kernel 2.6.16-2-686 (Debian Unstable) instead of the 2.6.17-686 I had been using when previously reporting problems, MIDI playback was perfect, even under heavy disk load. So it appears to be a problem with 2.6.17-686 kernel on Debian (which is compiled for SMP, unlike the other kernels I've run).
