Hi, I face troubles putting modem (Intel) and sound working together in Woody
on laptop asus L3800C (L3C). Separately both work fine, but as they are on the
same IRQ 11 initialization of one causes the other stop working. Is there any
solution like possibility of IRQ sharing, etc ... ?
Below I attach
lspci -v and cat /proc/pci
Thans a lot, Zdenek
