Here is the first of several individual patches to 2.6.3 for the pcnet32
driver.

The driver did not properly serialize accesses to chip registers, resulting
in reading/writing the wrong register.  This patch eliminates this problem
and gets rid of the cause of the symptom of 'bus master arbitration failure'.

It was easier to use generic_mii_ioctl than modify the current pcnet32_ioctl
routine with the necessary locks.  This has been re-tested on an IA32 system.
