to be sure, could you elaborate the symptom again and the detail of your system (kernel version, applied patches, ALSA version)? especially, please check the following: - loading the module and unloading it immediately works? - the port and irq number are correct, i.e. match with the resources listed on lspci? - playback (via aplay) works? does the system hang up at the start, during the playback or at the stop? - during the playback, does the count in /proc/interrupts increases? (check with another terminal) a typical reason of such a hang up is either the wrong spinlocks, unexpected infinite loops in the driver code, or the interrupt storms. if it's the interrupt storm, then it can be related with the hardware, often motherboard chipset, or BIOS version. or, could it be because of ACPI? did you apply it? ciao, Takashi ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/ _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
