I also got quite a few "Couldn't get a free page" messages while
testing the Olicom Token-Ring driver currently being developed,
especially if I was beating the disk hard at the same time -
e.g. unpacking kernel sources and such. This was on a 20 MB
486 w/ ISA bus only.

(The driver uses DMA for data transfer, so it needs 4 KB
buffers below 16 MB for the ISA cards - that appears to
trigger it)

I tried the old
echo "128 256 1024" >/proc/sys/vm/freepages
and haven't seen it since.
