Description Alan Cox 2004-02-14 15:31:52 UTC 
On an AMD dual athlon you need acpi=off pci=usepirqmask together.
Surely acpi=off should stop trying to use acpi routing data ?? 

[Box works reliably in 2.4]

It then later dies with a spew of oops data from a network operation
of some kind.
Comment 1 Alan Cox 2004-02-14 17:46:40 UTC 
Ok its crashing reliably on the ifconfig ifup of the network card
(netgear). 

dev->change_flags (hence I guess ifup)
dev->open
alloc_skb
cache_init_obs
then an IRQ coming in
and can't recover the top of the trace

So it looks like a network driver with incorrect irq protection
Comment 2 Alan Cox 2004-02-15 17:22:02 UTC 
Network oops turns out to be a side effect of the broke acard scsi
module it seems (that or its just chance that acard scsi puts the
corruption somewhere that matters).

Other stuff still the same
Comment 3 Dave Jones 2004-06-14 23:32:45 UTC 
how's things looking with the current kernel on this box ?

do we need to fiddle stuff based on dmi strings ?

Is it worth adding the acpi folks
(acpi-bugzilla.net) to the cc: of this bug ? or is
the DSDT too broken for them to work around?
Comment 4 Alan Cox 2004-06-14 23:40:31 UTC 
Will investigate further
Comment 5 Alan Cox 2004-10-01 22:30:07 UTC 
Works properly with FC3test2 so I guess the bug is fixed now
