It happens when there's a bit > of traffic (e.g. an 'ls -lR' of an NFS mounted dir). could you send "dmesg" and "mptable" output? (both cases - PCI-X enabled, PCI-X disabled) I am currently looking for evidence that shared irqs might lead to system hangs (=> irq stalls), if timing of all involved device drivers is 'right'. Subject says 'hang' - in your message you say 'crash'. What is the exact behaviour of your system? Eg can you still switch consoles (ALT-F1,...)?
