[[AmiloA]]
SAMUEL'S IRQ COMPARISON BETWEEN Windows XP and Mandrake Linux with Kernel 2.6.8.
He managed to use dri too
Maybe the differences are not that significant, but Windows shows us a “working” irq configuration.

[[AmiloA]] CONFLICT w/ LAN & DRI
This happended to me w/ Kernel 2.6.0-test5+
When using dri patches, They're some irq conflicts than forbid to use lan (8139too) at the same time, (bad implemation of irq sharing may be the cause, see resources about the enhanced interrupt controller (apic) ).
