Hallo,
When I boot a kernel with iommu=force (this forces all pci_map_sgs
through the K8 aperture) and slab debugging on a Nforce4 x86-64
system the network corrupts data very quickly. Even when just
sshing somewhere ssh quickly aborts with MAC errors etc.
Reverting only forcedeth.c to the one f

There are multiple nforce versions - which one do you use?
For example only the most recent one supports 64-bit dma, perhaps
something with the 64-bit code is broken

It crashes for me, too:
- nForce 3-250 Gb, in 100 mbit mode
- slab debugging on
- iommu debug and iommu leak enabled
- x86-64
- tx works.
- rx crashes.
Test case: "p
Some more testing shows that even the 2.6.14 driver eventually
causes slab debugging BUGs() like
