That's actually a W83C553 which does not support UDMA in any shape or form according to the documents. I guess it's an enhancement found on W83C554, and in that case any attempt to add UDMA support to the SL82C105 driver should be done such that these older chipsets continue to work. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
