Ok, all checked, no conflict.
I have disable all possible devices, the ex0 take either irq 10, 11 or 15,
and still same message.
I think it could be a problem with the chipset of my motherboard. Dmesg
output is like :
pchb0: Acer Labs M1541 Host-PCI Bridge (rev. 0x04)
pcib0: Acer Labs M1543 PCI-ISA Bridge (rev. 0xc3)

Motherboard is a GA-5AX with Ali chipset, socket 7 and a AMD K6-2 500Mhz
I can post the entire dmesg output, but will take a little time.
