Also what cards do you have in which slot. (Please also specify PCI or GSC). What this driver does is allocates a certian portion of memory at startup time for a TLB mapping. Adjusting the ccio_mem_ratio affects how much memory is allocated at boot. The U2/UTurn chip has 2 iommus, and the different GSC/PCI slots fall under specific iommus. If you system does not have much memory, and the cards are positioned approparately, we could turn off the iommu memory allocatation for the second iommu (the /10 bus). this is just a thought ... will see what we can do with your configuration :) Thanks, - Ryan On Fri, 2002-07-19 at 10:08, Juergen Braukmann wrote: > Hi Grant and all, > > still more tears.
