I worked around this problem by assiging a free irq in the BIOS
(MB A7N266, not a A7N8, dunno if the A7N8 BIOS gives you
this possibility)

xl0 is rock-solid since with APIC and ACPI enabled

YMMV, Arno

NB, I still get the interrupt storm on irq7 when attaching a
scratch P200 notebook by plip ...

NB-II, for Windows I use Samba and whatever I find a PC thrown on the street;
but then, I dont like computer games ...
