Are you guys aware of any problems related to APIC on Athlon systems? My system is: - MSI Computer nForce K7N420 Pro motherboard (NVidia chipset, GeForce2 embedded, nForce sound card embedded, network embedded): http://www.msicomputer.com/product/detail_spec/product_detail.asp?model=K7N420_Pro - AthlonXP 1800+ CPU - IEEE1394 (FireWire) card - Hauppauge TV card - Red Hat 8.0 fully updated - updated RH Athlon kernels - nVidia's latest drivers (GeForce and nForce) rebuilt by myself from src.rpm - ALSA latest drivers (0.9.something), compiled by me from sources For some reason, i can't get APIC working, and my interrupts are overcrowded, causing problems with time-sensitive applications (multimedia). I tried passing "apic" and "pirq=0" to the kernel, and play with BIOS options, but that didn't helped. Strange thing is, someone i know has the same type of motherboard (MSI nForce) and he has APIC enabled just fine (and he didn't do anything to get it working). But he's using a different Linux distribution (not sure which, but not Red Hat). As a workaround, meanwhile i killed LPT and COM from the BIOS (i wasn't using them anyway), so that i got more room for the IRQs. The system _appears_ to work somewhat better, but i need to do more testing. But that won't work anymore once i'll get the new IDE controller card, and possibly a SCSI controller too, because those things will eat up more IRQs. -- Florin Andrei "Were any orcs or 'dark men' offered coalition positions in King Aragorn's cabinet, at the end of the War of the Ring?
