1- SORRY FOR MY ENGLISH!!! (i'm italian)

I've got a problem with my laptop (Acer Travelmate 290 Centrino...).
If i set DHCP for the Realtek 8139 it doesn't connect, while if i set it to use a fixed ip it works without problem.

Under knoppix (3.3) the realtek uses IRQ 11, uder WinXP uses the IRQ 10.

No problem with winXP.

I've got a 3com office connect 812 (dhcp server)...

I tried ALL the "solution" found in the forum (noapic, patched kernel with acpi, pci=biosirq etc etc) without success....

PLEASE HELP ME!!!
