Trouble with swiotlb

[Roland Fehrenbacher]

Hi,

when building 2.4.28 or 2.4.27 on x86_64 with IOMMU and SWIOTLB support
enabled I get unresolved symbol for 3 modules:

depmod: *** Unresolved symbols in /lib/modules/2.4.28/kernel/drivers/net/e1000/e1000.o
depmod: *** Unresolved symbols in /lib/modules/2.4.28/kernel/drivers/usb/host/uhci.o
depmod: *** Unresolved symbols in /lib/modules/2.4.28/kernel/drivers/usb/host/usb-uhci.o

When modprobing any of the modules I get:
unresolved symbol swiotlb

The kernel boots fine on Opterons and EM64T Xeons otherwise.

Any ideas.

Cheers,

Roland
