Hello list, I have problem in handling interrupts of my pcm0 device. It consumes about 30% processors time continuously and it doesn't matter if I compile sound driver directly to the kernel or as a mudule. In the time of messurement I didnot play any sound or use this device for playing music. It is right after the machine boots. The top commands shows: 53 root -60 -179 OK 12K *Giant 0 28:29 36.33% 36.33% irq16: pcm0 Almost all time it is in *Giant state. I have dual Pentium III 450Mhz and ofcourse kernel compiled with SMP and APIC_IO. Thank you for any suggestion. Regards, Muff -- Potrebujete vice prostoru pro vase stranky?
