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: 06-27-2006 23:43 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 - 06-08-06 09:28 ---------------------------------------------------------------------- A kernel panic message---good idea :-) http://www.iskunk.org/tmp/alsa-kernel-panic.jpg (1.1 MB) (I tried to upload this here, but the PHP threw an "out of memory" error...) ---------------------------------------------------------------------- phorn - 06-27-06 23:43 ---------------------------------------------------------------------- I am also getting this bug pretty often (kernels 2.6.15 through 2.6.17.1). I get no useful indication when using SMP. The only way to tell is that "pmidi" frezes in the "running" state, and half of the I/O devices (keyboard, ethernet and sometimes harddrive) stop working. I decided to disable SMP and then I got a nice kernel message which I attached as kernel_spinlock-2.6.17.1-nosmp.txt 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 ====================================================================== Using Tomcat but need to do more?
