Well, sideways ofcourse! :-) here's a cat /proc/interrupts from the (BP6) box: CPU0 CPU1 0: 104936 105433 IO-APIC-edge timer 1: 4444 4384 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 3: 79 59 IO-APIC-edge serial 4: 12743 12850 IO-APIC-edge serial 14: 7855 7885 IO-APIC-edge ide0 15: 1990 1703 IO-APIC-edge ide1 16: 0 0 IO-APIC-level es1371, mga@PCI:1:0:0 17: 24 28 IO-APIC-level sym53c8xx 18: 0 0 IO-APIC-level bttv 19: 460435 460402 IO-APIC-level eth0, eth1, usb-uhci NMI: 210303 210303 LOC: 210285 210284 ERR: 0 The interrupt which caused problems was 19 (with both network cards and USB on it). It shows a high number of interrupts because I've been load-testing the network. The mere fact that it shows this hig number of interrupts shows the fix works... As this is a BP6, I'm now supposed to go on about the dead chickens, dedicated air conditioners, nuclear powersupplies and other magic you're supposed to buy to get these boards running. Well, nothing of that sort, it is running on a simple (but high quality) 235W PSU with heatgreased coolers on the CPUs and the BX xhipset. Nothing is overclocked. CPU and chipset tmeperatures are 24.C and 32.C, respectively. In short, nothing remarkable. All PCI slots are used, as you can see from my first posting in this thread (which contains more info on the hardware). //Frank -- WWWWW _______________________ ## o o\ / Frank de Lange \ }# \| / \ ##---# _/ \ #### \ +31-320-252965 / \ frank@unternet.org / ------------------------- [ "Omnis enim res, quae dando non deficit, dum habetur et non datur, nondum habetur, quomodo habenda est." ] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
