You didn't say, but is there any chance you are running that UP2000
with more than 2GB of memory? If so, then be aware that the stock
DAC960 driver has NOT been ported to use the large memory API.
If you DO have more than 2GB of memory, a simple test to see if this
is the cause of the problem would be to boot limiting memory to 2GB,
ie, add "mem=2G" to the boot command line.
If this is indeed the case, I do have some (unofficial) patches to
the DAC960 driver which appear to work for large memory configurations.
Let me know if you want them.
