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

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).
