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: 07-03-2006 02:57 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? ====================================================================== ---------------------------------------------------------------------- amarsh04 - 07-02-06 15:37 ---------------------------------------------------------------------- I'm having the same kind of problem, apparently related to a combination of MIDI file playback and heavy disk activity: I initially thought I had a problem with denemo, but was able to reproduce a complete system lockup when playing MIDI files, given sufficient hard disk activity using: aplaymidi -p17:0 playmidi -a kmid The first 2 were tried under twm, all 3 methods were tried under KDE. Any suggestions on further debugging steps welcome. -- Package-specific info: --- Begin additional package status --- Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii libasound2 1.0.11-7 ALSA library --- End additional package status --- --- Begin /proc/asound/version --- Advanced Linux Sound Architecture Driver Version 1.0.11rc4 (Wed Mar 22 10:27:24 2006 UTC). --- End /proc/asound/version --- --- Begin /proc/asound/cards --- 0 [Live ]: EMU10K1 - SB Live 5.1 [SB0220] SB Live 5.1 [SB0220] (rev.10, serial:0x80651102) at 0xe400, irq 11 --- End /proc/asound/cards --- --- Begin /dev/snd/ listing --- total 0 crw-rw---- 1 root audio 116, 0 2006-07-03 07:51 controlC0 crw-rw---- 1 root audio 116, 4 2006-07-03 07:51 hwC0D0 crw-rw---- 1 root audio 116, 6 2006-07-03 07:51 hwC0D2 crw-rw---- 1 root audio 116, 8 2006-07-03 07:51 midiC0D0 crw-rw---- 1 root audio 116, 9 2006-07-03 07:51 midiC0D1 crw-rw---- 1 root audio 116, 10 2006-07-03 07:51 midiC0D2 crw-rw---- 1 root audio 116, 24 2006-07-03 07:51 pcmC0D0c crw-rw---- 1 root audio 116, 16 2006-07-03 07:51 pcmC0D0p crw-rw---- 1 root audio 116, 25 2006-07-03 07:51 pcmC0D1c crw-rw---- 1 root audio 116, 26 2006-07-03 07:51 pcmC0D2c crw-rw---- 1 root audio 116, 18 2006-07-03 07:51 pcmC0D2p crw-rw---- 1 root audio 116, 19 2006-07-03 07:51 pcmC0D3p crw-rw---- 1 root audio 116, 1 2006-07-03 07:51 seq crw-rw---- 1 root audio 116, 33 2006-07-03 07:51 timer --- End /dev/snd/ listing --- -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.17-1-686 Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8) Versions of packages alsa-base depends on: ii linux-sound-base 1.0.11-2 base package for ALSA and OSS soun ii lsof 4.77.dfsg.1-3 List open files ii module-init-tools 3.2.2-3 tools for managing Linux kernel mo ii modutils 2.4.27.0-6 Linux module utilities Versions of packages alsa-base recommends: ii alsa-utils 1.0.11-4 ALSA utilities Versions of packages libasound2 depends on: ii libc6 2.3.6-15 GNU C Library: Shared libraries -- debconf information: alsa-base/alsactl_store_on_shutdown: always autosave ---------------------------------------------------------------------- amarsh04 - 07-03-06 02:57 ---------------------------------------------------------------------- I also reproduced the bug from text consoles, running "playmidi -a somefile.mid" in one vt and "aptitude -u" in another.
