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: 07-02-2006 15:37 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 - 06-28-06 03:50 ---------------------------------------------------------------------- I just tried the alsa-driver and alsa-kernel from your hg repository, running on the same kernel with the built-in ALSA disabled, and I get the same kernel error after letting "pmidi" run for a few minutes. I also noticed that the OSS emulation (sfxload and playmidi) now work with the latest ALSA from Hg, however using those programs produce the same crash. The version file in the alsa-driver directory from HG has "1.0.12rc1". The built-in ALSA, according to /proc/asound/version is "1.0.11rc4". ---------------------------------------------------------------------- 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 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 06-07-06 18:09 pen Issue Monitored: pen 06-07-06 18:23 rlrevell Note Added: 0010086 06-07-06 19:45 pen Note Added: 0010087 06-07-06 19:50 rlrevell Note Added: 0010088 06-08-06 09:28 skunk Note Added: 0010109 06-27-06 23:35 phorn File Added: kernel_spinlock-2.6.17.1-nosmp.txt 06-27-06 23:43 phorn Note Added: 0010602 06-28-06 00:03 rlrevell Note Added: 0010603 06-28-06 03:50 phorn Note Added: 0010605 07-02-06 15:33 amarsh04 Issue Monitored: amarsh04 07-02-06 15:37 amarsh04 Note Added: 0010791 ====================================================================== Using Tomcat but need to do more?
