I'm desparately seekeing a wizard that may be able to help me solve this problem. I fear nothing short of a wizard is what it will take.
I have an Averatec 3250 running Mandriva 2006 with ACPI enabled. I must have ACPI enabled to use the USB ports on this laptop, and besides, without it, the battery life is crap. When I try to connect the network (using "ifup eth0") I receive a message from the kernel that IRQ 11 is being disabled and (if the system does not hang right there) the network will not come up at all. If I use the kernel parameter "pci=noacpi" then the network works fine, but the USB ports are not functional.
I have tried the following kernel parameters with no success:
nolapic
noapic
pci=pirqmask
pci=biosirq
irqpoll
acpi=bios
acpi=noirq
The dmesg output after attempting to bring up the network with the ACPI enabled is as follows:
via-rhine.c:v1.10-LK1.2.0-2.6 June-10-2004 Written by Donald Becker

Disabling IRQ #11
If anyone can help me interpret what this means and figure out how to fix it so I can use both my network AND my USB, I would be forever greatful.
Thanks in advance.
