I have been running into the problem briefly mentioned at the wiki entry http://alsa.opensrc.org/index.php/Toshiba_Tecra_500CDT. Playback using the CS4232 driver in native or oss emulation mode fails randomly. Once the failure occurs, subsequent attempts to playback stop shortly after opening the device and tickling the speakers (perhaps the buffer gets filled once). Under heavy network load, the initial failure will occur rather soon, within 15 minutes or so of playback. When I am playing songs from the hard drive, the failure takes a very long time, and when I use oss emulation and play from the harddrive, I have been unable to replicate the bug. The CPU does have the F00F bug if that might make some difference. I have attached a backtrace resulting from the attempts to use aplay after the failure has occurred. I may be able to attempt to capture a backtrace at the initial failure if this would be helpful. There are no obvious error messages in my logfiles or printed to the console when the bug occurs. Please let me know how I can assist in squashing this bug. I attempted to use the alsa-info script, but it appears that the database where it uploads the results is broken at the moment. I have pastebinned the results at http://pastebin.ca/1315459 Thanks Stanley Pinchak
