Hi there, I have tested the last SOUND example but it doesn't work for me with RedHat 5.2 and RTL 1.1 All over examples work fine! If I try with the old sound example it works!! I don't see why the irq can't be requested by init_module. I try a lots of things but nothing new... Somebody else has the same problem? Any idea? Thanks Here are some screens : make test ..... insmod /usr/src/rtl/modules/rtl_fifo.o insmod /usr/src/rtl/modules/rtl_sched.o make: [test] Error 1 (ignored) ./sound.o: init_module: Busy make: *** [test] Error 1 INTERRUPTS 0: 60872 timer 1: 385 keyboard 2: 0 cascade 4: 18844 + serial 13: 1 math error 14: 33066 + ide0 15: 0 + ide1 IOPORTS 0000-001f : dma1 0020-003f : pic1 0040-005f : timer 0060-006f : keyboard 0080-009f : dma page reg 00a0-00bf : pic2 00c0-00df : dma2 00f0-00ff : npu 0170-0177 : ide1 01f0-01f7 : ide0 02e8-02ef : serial(set) 02f8-02ff : serial(set) 0376-0376 : ide1 03c0-03df : vga+ 03e8-03ef : serial(set) 03f0-03f5 : floppy 03f6-03f6 : ide0 03f7-03f7 : floppy DIR 03f8-03ff : serial(auto) --- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] ---- For more information on Real-Time Linux see: http://www.rtlinux.org/~rtlinux/
