I was frustrated. > But I found a workaround: Turning off ACPI. dunno, I'd more suspect ACPI<->APIC issues : untill now I only had problems on nForce based systems, but today I=20 installed a brand new VIA based A7VT mini-server and re-voila les "XXX_DMA" errors (and accompanying severe system slow-down). (Disk swapped from the old PII-233 minimalist-server; worked OK there; disabling APIC (in BOIS and/or config and/or hints) made disappear the XXX_DMA messages (and gave me my network connexion back ;) ) whilst ACPI still enabled).
