The interrupt timeout problem appears to be caused by ich_intr() no longer seeing what it thinks are valid interrupts from the device. Guido sent me some useful debug info and we are homing in on the problem. The ACPI vs. non-ACPI difference that you are seeing may indicated that the problem is triggered by interrupt routing and/or what other devices share the same IRQ as the sound hardware.Received on Tue Sep 07 2004 - 14:56:36 UTC
