--0-1815627535-1077515856=:19519 Content-Type: text/plain; charset=us-ascii Content-Id: Content-Disposition: inline Hello Hackers, My system: $ uname -a FreeBSD apsara 5.2.1-RC FreeBSD 5.2.1-RC #0: Sat Feb 7 21:38:15 PST 2004 root@apsara:/usr/src/sys/i386/compile/APSARA i386 $ dmesg | grep pcm pcm0: <CMedia CMI8738> port 0xd400-0xd4ff irq 16 at device 14.0 on pci0 (full dmesg output attached) Occasionally my system will lock up when audio files are played. I am using the pcm driver with a CMI 8738 on-board 6-channel audio chip (SoyoPX400 Dragon Lite motherboard). No crash dump, no panic message is displayed; the system just freezes. It does not happen regularly--probably only once in 10 or 20 times that the audio device is used. When it does happen, it can happen immediately after the audio file is played, or sometimes after several seconds. A quick search of the -hackers and -questions archives didn't turn up any matches. Has anyone else seen this behavior? Would it be more useful for me to build a debug kernel with INVARIANTS enabled and try to get the system to panic? Thanks! -brian __________________________________ Do you Yahoo!? Yahoo!
