And we have no memory available in the DMA zone. But this is an ISA DMA
zone (first 16 MB of bus addresses). Why would it need memory in that
range? Maybe its DMA mask is no longer initialised correctly (pata_via
doesn't set it explicitly, but for PCI devices it should normally be set
to DMA_BIT_MASK(32) by default).
Can you test some intermediate kernel versions to narrow this down?
There should be several on snapshot.debian.org.

The program is absolutely right; therefore, the computer must be wrong.
